Ungroup functionality and ClientReliableUpdate improvements

[sourencho]

Fixes #4

[355e16d] Rename game_state to StateDef

[4c8adfd] Client ungroup command and client update improvements

• Client now has inputs for ungrouping (ESC) and for stopping (SPACE)
• Client reliable and unreliable updates are now passed to the game state with player_id attached instead of client_id. This is so that the non networking code doesn't need to deal with conversions from client_id to player_id. Ideally it wouldn't even know what a client_id is.

[a719a04] Reassign groups based on players' ungroup property

• Players can now ungroup by pressing ESC.
• For now players are moved to a group at the (0,0) location. This will change to a location near their original group probably.
• Apparently pressing ESC doesn't guarantee that you are ungrouped. I suspect this is because of the way we send reliable updates. I will attempt to fix this in a follow up change. Currently pressing ESC once will flash your new group due to interpolation but it is reflected only on the server if you're lucky. Spamming ESC eventually ungroups lol.
• Create a new TypeDef header file

[123b7d4] Add minor todo

[2eb5490] Send reliable update toggles instead of values

• Only apply player inputs once in an update. Before we were applying it every step (there can be multiple steps in an update). This was problematic because if there were two steps in an update then an ungroup toggle would apply twice and not have any effect.
• Display ungroup status in group for debugging purposes.
• Only set reliable update if any of the toggles are true.
• Move handle events into ClientGameController from client/main.cpp

[a975ab1] Add utility functions to ClientReliableUpdate

[6ad39e1] Minor improvements

• Groups now spawn near eachother when they ungroup. Unfortunately this causes collision (#105)
