-Implement GM command collect (subtracts gil from player), but the ingame command's params are unknown, Lua only
-Implement GM command inspect, but the IPC opcode for it is different than GMCommand and is thus far unimplemented, Lua only
-The Lua API can now access all of the player's inventory (read-only)
This removes a ton of implementation overlap between the two
command systems. For example, we had two different implementations
of unlocking aetherytes which is just unnecessary.
On the flipside, this makes implementing new GM commands just as
easy as writing debug ones. I moved the existing debug Lua
implementations into their GM counterparts and updated the USAGE
accordingly.
