Graph Editor "Active Keyframe" settings

This commit makes some tweaks to the way that the "active keyframe"
settings in the Properties region in the Graph Editor work (for the
better, hopefully).

Basically, the problem was that previously, these were clunky and non-
intuitive to use, since they were just directly displaying the RNA
properties for those keyframes for editing purposes. But due to
limitations of RNA (i.e. from a RNA pointer to a keyframe, you
couldn't see which F-Curve you came from), several things were
impossible, notably:
1) Doing proper updates, including validating that the handles are in
a valid state - that requires access to the F-Curve to provide to the
F-Curve-based curve validity checking functions
2) Having the values of the keyframes display in whatever unit that
the property the F-Curve affects displays as - for this, you once
again need to know the F-Curve in order to resolve the property that
it affects; also the fact that only a single unit could be set for RNA
properties further limited things

This commit basically gets around these problems by moving away from a
layout-engine based approach to one where we attach custom update
callbacks and also override the units of the y-co widgets when
creating the widgets for these, thus allowing the buttons to work in
the ways that animators expect.

for UI text drawing use BLF_ascender(fs->uifont_id) rather then BLF_height(fs->uifont_id, "2"), while profiling draw noticed that the hash lookup on the character and utf8 next were being called on every text draw, use BLF_ascender since it doesn't do any lookups.

Material ray trace transparency animation COLLADA export.

remove copy modifiers function, now handled in link data operator.

BGE Animations: Making the ping pong mode for action actuators behave more like trunk. The behavior is a lot closer, but there are still differences when interrupting a ping pong action. I'm still trying to decide if these are acceptable differences as they don't look all that simple to fix.

KEYMAP REFACTORING

Diff Keymaps

User edited keymaps now no longer override the builtin keymaps entirely, but
rather save only the difference and reapply those changes. This means they can
stay better in sync when the builtin keymaps change. The diff/patch algorithm
is not perfect, but better for the common case where only a few items are changed
rather than entire keymaps The main weakness is that if a builtin keymap item
changes, user modification of that item may need to be redone in some cases.

Keymap Editor

The most noticeable change here is that there is no longer an "Edit" button for
keymaps, all are editable immediately, but a "Restore" buttons shows for keymaps
and items that have been edited. Shortcuts for addons can also be edited in the
keymap editor.

Addons

Addons now should only modify the new addon keyconfiguration, the keymap items
there will be added to the builtin ones for handling events, and not get lost
when starting new files. Example code of register/unregister:

km = wm.keyconfigs.addon.keymaps.new("3D View", space_type="VIEW_3D")
km.keymap_items.new('my.operator', 'ESC', 'PRESS')

km = wm.keyconfigs.addon.keymaps["3D View"]
km.keymap_items.remove(km.keymap_items["my.operator"])

Compatibility

The changes made are not forward compatible, i.e. if you save user preferences
with newer versions, older versions will not have key configuration changes that
were made.

Messed up char was causing problems on windows even though it was in the
comments.

Camera tracking integration
===========================

Interpolate camera location and orientation for frames
where's no reconstruction data.

This fixes motion blur compositor node (first and last camera's
position was at origin, so motion vector was totally incorrect).

fix for GHOST/SDL key input with uppercase keys.

ifdef out support for for python owning and freeing BPy_StructRNA because this is only used for doc generation and it makes _every_ blender/python instance 4 bytes bigger - vertex/bezier point/object/scene/group etc.

pyrna - add own callable function type rather then using a standard python method, gives small speedup drawing buttons since every layout.prop/col/operator/menu etc creates and throws away one of these.

move the ndof menu into the userpref's since it adjusts preferences, also renamed VIEW3D_MT_ndof_settings -> USERPREF_MT_ndof_settings since it has no view3d specific settings.

Timeline UI Nitpicks:
* "Only Selected channels" -> "Only Selected Channels"
* Use Keying Set icon for "only keying set" toggle for autokeying

patch from jensverwiebe to scons to be compatible with gcc llvm. people who copy the darwin-config.py to their user-config.py should update.

Camera tracking integration
===========================

Added back Scale factor for scene orientation in toolshelf.
But now it's used in a bit other way -- invoke function
checks if operator's property is set and if not -- value
set in toolshelf is used.

Bugfix [#28106] Missing 3D view update after copy of constraints

Assorted loose ends for auto-clamped handles work
* Tweaked order of handle types to make it easier to find Auto/Auto-
clamped in the list
* Fixed a number of places which were still just checking for auto-
handles when they should have included auto-clamped too, including
handle rotation

fix for icon scaling with the DPI setting
- icons were scaling by the sqrt(dpi)/8.48528, but infact they only need to be scaled by (dpi/72).
- UI_icon_get_width value was being used without multiplying by dpi scale.
