Fixed a bug in MyCharacterStateChunkProcessor in character (thick,
profile) processing. 
In ChunkerChain, moved ThatChunker behind When/WhereChunker.
Made When/WhereChunker forming limit to unassigned when/where terminals.
Made Statement text to hold the original sentences to keep letter case,
which is useful in StructureNameStandardizer. 
Updated perl singular function with more special cases.
Fixed a format issue in CharacterListChunker ({colorationttt).
Allowed more area expressions to get in the area normalization.
Added checks for null pointers in StructureNameStandardizer: these
didn't throw exceptions but caused problems in thread latches count
down.
