Cleanup|World|BspLeaf: Removed all obsolete BspLeaf accessor methods
A BSP leaf should not be thought of as a "subsector" as this produces too strong of a binding with the much higher level "sector" concept. (Also resulting in a wide and heavy API at BspLeaf level.)
If one wants sector and/or plane properties at a BSP leaf, the sector cluster is now dereferenced explicitly. (Which should help to guide future map data development in the right direction.)
