- Removed generational garbage collection from the string pool because it didn't

actually work.
- Turned the list of TabCommands into a TArray because I saw lots of console
  commands in the memory leak report at exit. Then I realized those were actually
  key bindings, so I changed the Bindings and DoubleBindings arrays into FString
  arrays.
- Fixed: FStringCVar was missing a destructor.
- Added TArray::Insert().
- Fixed: TArray::Delete() used memmove().
- Renamed Malloc(), Realloc(), and Calloc() to M_Malloc(), M_Realloc(), and
  M_Calloc() so that the debug versions can be defined as macros.
- Enabled the CRT's memory leak detection in WinMain().
- Moved contents of PO_DeInit() into P_FreeLevelData().
- Removed "PolyBlockMap = NULL;" from P_SetupLevel(), because the P_FreeLevelData()
  call it makes next does the exact same thing, but also freeing it if needed.
- Fixed: Unneeded memcpy in UnpackUserCmd() when ucmd and basis are the same
