Weight Paint: restore non-spray functionality

Browse Source 
When painting with spray disabled - we need to re-apply
on top of the original each time.

Applying the soc-2016-pbvh-painting branch removed this.
While I'd added back a simple previous weight array,
this won't work when multiple groups are painted at once.
