Vertex Paint: remove accumulate (soc-2017-vertex_paint)

This secondary accumulation option accumulated brush falloff.
The same option in image painting accumulates color
as vertex paiht 'Spray' does.

Giving this option different behavior for vertex paint seems strange.
Also this is basically increasing falloff over time.

Remove the new code, expose existing 'Spray' as 'Accumulate'
to match other paint modes.
