Setting "select" property on GP Points via RNA now syncs the selection status with the stroke

This is a bit clumsy as RNA doesn't give us this info on a plate...

GP Stroke Edit: Individual points can be transformed

Locked GP Layers cannot be edited at all - Not even for selection

GP Stroke Editing: Individual stroke points can now be selected

The selection status of a stroke depends on whether there are any selected points.
Without any selected points, strokes will not be selected.

Drawing Test: Use theme setting for the base colour of unselected GP Verts when opacity < 1

The intention here is that in this case, the unselected verts will no longer stand out
enough when full opacity is used, as they would all be the same colour.

Added a dedicated way of drawing selected strokes and their points

This currently uses the theme setting for vertex size for the selected colour of
strokes. For the unselected colour, it still uses the colour of the stroke itself,
which only works well when the strokes are not fully opaque, and also if the
colour of the stroke is not the same as the selected colour.

Drawing code refactoring: Move out logic for testing if a stroke can be drawn into a separate function

Bugfix: Wrong label for scale operator in toolbar

DNA support for tagging individual stroke points as being selected

Code cleanup - Replace #defines with enums

GPencil Strokes - D+M can be used to mirror strokes now

Grease Pencil Dopesheet - Selecting channels in the dopesheet changes active layer

Fix: Node editor redraws properly after stroke selection changes

Toolbar buttons for Grease Pencil editing operators

TODO: Next up, a Pie Menu (bound to DKEY) would be a nice complement for this

GPencil Stroke Duplicate operator is now a macro which combines the copy and move into a single step

Fix: Resolved crash when toggling selection of strokes

Fix: Skip recalc_data() processing for strokes

This isn't needed right now, but it also shouldn't just fall through to object handling

Add more sanity check error prints

Bugfix: Fix for crash after transforming strokes

Transform tools for Grease Pencil strokes

Selected strokes can now be transformed (translated, rotate, scaled), using:
* D+G = Grab/Move
* D+R = Rotate
* D+S = Scale

Things are still rough around the edges though, and may not work well in all
cases yet. Known todos:
* There's an occasional crash after duplicating and moving a stroke
* 2D strokes (and other editors) may not work well yet
* Need to check on the case when there is no active object
