Trimming support base layer with brim.

Browse source 
Fixes Brim destroyed by support aka. Enable supports on top of brim #1156
Fixes Brim Priority/Support on Brim #713
Fixes Phantom Support columns interfere with brim #3396
Fixes false generation of brim when supports are used #3395

This is a work in progress, as the brim generator currently produces
different brim areas from what the support generator expects.
