RankMgr: Implemented GetXforY and GetAll APIs.
RankMgr: Finished API implementation.
cLuaState: Added GetStackValues() auto-generated templates.

These will read consecutive values off the stack, each value of a type independent of the other values.
Auto-generated because we don't have variadic templates in C++03.
Exported cRankManager to LuaAPI.
Debuggers: Simple cRankManager test case.
