Changed include paths to relative paths, and added an agnostic struct.

The agnostic struct consists of a 'Mode' enum, and a 'Sock' type. The
'Sock' can be either a Server or Client, depending on the type of game.
This allows polymorphism, as I don't have to worry about whether the game
is being run in Server or Client mode, and I can call the same methods regardless.
