Added GlobalSettings Class

Created a Class in which global settings can be queried. Currently there
is only one setting: Max IP Connections.
Removed Unneeded Import

The LoginObject Class no longer needed the import java.security.Key
Hooked To Global Settings

Changed the IPMap Class to check the global settings for the assigned
maximum amount of connections per IP.
Fixed NullPointerException

Because the SocketChannel wasn't set in the event, it caused methods
(all of them were @EventHandler methods) which required a SocketChannel
to operate properly set a variable inside NIOS to be null causing a
NullPointerException inside the NIOS run() method.
Compressed Code
