Fix T61689: Crash when having image and regular animation

Was caused by ambiguity in entry/exit operation for animation channel.
Made those explicit now,

Depsgraph: Simplify creation of animation nodes

Cleanup: Indentation and wrapping

Measure Tool: delete now removes protractor when it's active

Measure Tool: use x/del key to remove the active ruler

Dragging outside the view was only meant to be a temporary workaround.

Cleanup: rename keymap handler callbacks for clarity

Now there are two callbacks, the name 'keymap_callback' is too vague.

WM: support dynamic keymap handlers

Add getter callback support for 'WM_HANDLER_TYPE_KEYMAP' type handlers
this is needed for key-maps which change based on the active tool.

Replaces 'sneaky_handler' hack which temporarily inserted a handler.

RNA: use factor when appropriate

- Many factor properties were set to PROP_NONE,
even properties that had 'Factor' in the name!

- Some time properties were not set to PROP_TIME,
especially in Particles.

- Changed motion_blur_shutter to use a soft max value of 1 instead of 2.
Anything > 1 here is not physically correct
and makes no real logical sense.

- Changed display name of Dynamic Paint dissolve_speed to Dissolve Time,
since it's a time property, not speed.

Cleanup: rename generic handler -> handler_base

Avoids having type specific handler names.

Cleanup: simplify handler type conditional

Each handler type now has it's own block (fileselect was an exception).

Cleanup: rename wmEventHandler_* base -> head

Makes it more clear it's the header/start of the struct.

Cleanup: use iterator macros for event handlers

BLI_listbase: add an iterator macro that supports removal

Avoids manually defining 'for' loops that store the next item in the
linked list.

EEVEE Shader comments: Explain why material gets darkened when using mix shader

We are still ditching the specular intensity of SSR (ssr_data.xyz).
But at least now there is some comment about it.

See T61704 for user reports on that matter.

Comments with the blessing of Cl�ment Foucault.

Comment: clarify reason for using scale as size

Cleanup: style

Fix T61696: Filepath buttons not accepting empty values

The reported case was with the render output filename,
however the same was happening for file open.

Bug introduced on c20c203b82260c06888c2a535c08ec383923ee8a.
I can't find in the original commit any reasoning for the change
that introduced this bug.

Merge branch 'blender2.7'

Fix T61701: Orthographic Viewpoints Hidden Grid

If all axis and grid options were turned off, the grid in the main ortho views would not be rendered.
Now we force rendering of the grid regardless of the settings when in one of the main ortho views.
