Removed windows specific files since the code is the same for linux
UdpClient: added basic methods to interact with the variables of that class, added initialization and started with sending and receiving messages
UdpServer: added initialization and basic variables
Utility: added a bunch of methods to the StringConverter utility class
VoidNetClientAPI: SendMessage now checks if message is not an handshake

initialization code for other operating systems - currently VoidNet only supports windows
initialization code for tcp client and tcp server for other operating systems - currently windows only
handle SendNetworkMessage errors for windows
handle ReceiveDataArray errors for windows
revamped BitConverter class
new StringConverter class
IPUtil class for other os's
maybe i should implement error codes
maybe i should implement error codes and exceptions
plugin system - idk how im going to implement it yet
maybe i should use virtual methods for the server and client, maybe...
TcpServer::SendMessage rework
