Tool System: Updates for keymap stored as string

Fix factory-settings using stale preferences

We need to reload defaults on factory startup because the defaults
now have preferences that may have changed.

Tool System: store keymap name in tool instead of the keymap

Resetting keymaps caused them to become invalid (crashing on access).

Keymap: always show pie menu w/ tab-pie-menu pref

Wasn't working well with armatures used ctrl-tab
to switch to pose mode, making tab always switch to pose mode
w/ this preference enabled.

Now always show pie-menu.

Keymap: Use Z to toggle wire instead of xray

This now works like 2.7x more or less exactly,
x-ray is enabled by default for wire so unless users change this,
it will enable x-ray too.

Keymap: 3D view pref for tab to show pie menu

This behaves like the 2.7x pie menu add-on,
for users who prefer single-key access to all modes.

UI: Add Image and Clip space panels category.

Pretty much all were missing those here... Put all in same category for
image, tried to sort them logically for Clip, since we already had at
least two (stabilization and 'misc')... sigh.

Another topic for UI team to work on I guess.

UI: First batch of fixing missing categories for panels.

Cleanup: Move debug warning message about panels missing category from drawing code to registering code.

In drawing it was pretty stupid (since we did not know *which* panels were
affected), and really, really annoyingly noisy!

UI: hide keymap preferences when filter is used

Keymap: correct error in grease pencil change

Keymap: remove annotation keymap editmode toggle

This is now used for grease pencil objects.

Keymap: Adjust shading key bindings

- 'Z' now toggles xray
(convenient, 2.7x-like binding to show occluded).
- 'D' shows the draw-type pie-menu.

Keymap: remove D-Key shortcuts for annotations

Use tools for annotations instead.

3D View: move x-ray toggle to operator

Allows binding to a key.

Keymap: use Ctrl-Tab to toggle fcurve/graph editor

Suggested by Pablo Vazquez.

Keymaps: take into account DPI for tweak/drag/pie thresholds.

The intention is to fix a too low default threshold on high DPI screen.
Users with high DPI screens that have increased the threshold to fix this
or liked the lower threshold will need to lower it again.

This is still somewhat of a guess, ideally this would be based on the
physical distance travalled, and maybe different per type of input device.
However we do not have access to this information, and hope this gives a
better default.

Keymaps: a few small improvements.

* Annotation tools now have Alt+LMB as for erase, like sculpt.
* In the LMB keymap, Shift+RMB drag now transforms 3D cursor for easy snapping.
* Curve edit mode draw is now only availble as tool, solves 3D cursor conflict.

Python API Docs: better titles.

The HTML title did not make it clear that these are docs for the API rather
than a general Blender documentation. Some of the page titles were also too
long and redundant.

Cleanup: warnings
