Implemented SharedParameters system in the client (read more)

Here are more tweaks:
* InWorld's quit event now exits to the main menu, bypassing a relayed disconnect message
* InWorld's disconnect hander no longer throws exceptions (dropped creation packet bugfix)
* CombatData's internals now point to std::pair objects
* Enemies are stored in a global list
