Merged network changes from branch 'develop', read more

After several days of trying, I decided to discard changes to the networking system:

> discard-encapsulated-packets

Instead, I've moved the packets and specialized serial functions into the same directory, and renamed them accordingly. The serialization code is only accessed by UDPNetworkUtility.

I've also removed the combat and enemy code from the network system, and reduced the number of packet types in SerialPacketType. These changes should make it easier to add more features in the future.

+Tortuga is a 2D multiplayer JRPG featuring permadeath (deletion of a character upon death). The emphasis of this game is on multiplayer cooperation, exploration and customization. The game runs on customizable server software that can support up to 150 simultaneous players or more.
 
 This game is inspired by classic 2D RPGs, as well as more modern sandbox MMOs. This project is currently independently created and funded, with the goal of creating a game that will engage user's imagination and inspire a large modding community.
