Fixed a possible buffer overflow in r_or() and r_sub() (thanks to Ingo Weinhold for his advices), stripped BRegion of all his friends, and moved them into a single class (BRegion::Support()). Removed "find_small_bottom()", as we didn't use it at all. Added some debugging output to BRegion::Support (that will help fixing bugs)
