#Additions
- added changelog
- added SocketManager which acts like a communication interface you can connect to and interact with ManiaControl (also thanks to TGYoshi for some help)
- added CommunicationManager which acts like a communication interface you can connect to and interact with ManiaControl (also thanks to TGYoshi for some help)
- You can call ManiaControl from a Website or from ManiaControl itself
- added "//removerights login" command
