* discard excess portals in the void (great optimization for maps with void areas in between of playable areas and non rectangular maps)

Browse Source 
(excess portals there are effect of _blocksize)
	* optimize FloodPortals() (also fix stack depth crash in debug mode due to recursive calls)
	* fix xml_Select() of leaked entity (was selecting last map entity always)
	* xml_Select() leaked entity exactly in the beginning of leak line
