Removed Fill/ReadNetworkData

These functions needed to be replaced because they rely heavily on reliability.

Instead, new functions called (Write/Read)Data(Server/Client) will be added. 

Separating client and server code into completely separate functions will help ensure that proper security checks are performed.
