GP: Draw Mode: Add Arc Primitive
This adds an elliptical arc primitive.
Press CKEY for toggling closed/open arc.
Press FKEY key for flipping arc.
Additional changes to gpencil primitives.
Increases default edges of circle to 64.
Keymap changes to allow primitives to be drawn with Shift or Alt key.
Allow Plus/Minus key to adjust number of edges.
Missing: Toolbar icon
