- Started adding action function declarations to objects.

- Added integer constant declarations to objects.
- Added some new token-based functions to sc_man.cpp that know about keywords
  and record proper type information, so parsers don't need to treat
  everything as strings.
- Added a simple symbol table to PClass.
