CR 3010449. Use GetTempPath to get appropriate location for EPICS error temporary file

Eliminated the last build warning, at least under VC++ 2003

Changes to compile with VC++ 6 as well as newer versions

Scripting uses hashes of keywords, including object-type, property-ids etc. The precomputed values were several revisions behind. Changed to COMPUTE the hash tables for object-types, property-ID, abort and reject reason, services - the enumerations that are expected to change most frequently
Eliminate stPropIDs - use the StringTable version instead to reduce maintenance
Eliminate unused tables from StringTables.cpp
Make case and punctuation of strings in StringTables.cpp match 135-2008
Add reserved and extension counts to StringTable, to allow eventual replacement of the redundant etables
