Replaced a ton of ConsoleMethods with the DefineConsoleMethod Macro.

Cleaned up the ConsoleMethods and converted them to DefineConsoleMethods.  Mainly the ConsoleMethods left are the ones that take a variable amount of parameters.  They will need to be cleaned up  in a later pass.
Unrelated changes for both `Engine/source/T3D/missionMarker.cpp` and `Engine/source/T3D/missionMarker.h` files.
