Easiest bit of the command rewriting work
Next wave
Last bit of the non-game-cmd refactoring
Rename the command queue related functions to start with cmdq_ for clarity
Rewrite the arg passing system in game-cmd.c
Move more spell studying logic from frontend to backend, and start moving command args across to named from unnamed
Start switching over args for functions to new struct away from old args setup
Rename cmd_get_* to cmd_get_arg_* and reorganise header files to avoid dependency hell.
Get more stuff compiling
Get the damn thing compiling, w00t
Add a TODO for finishing off this branch.
