notification.dart is used to handle the server side notifications. It allows for messages of different types, and gives the developer the ability to easily turn notifications off so that no i/o is being committed.
notification now prints colored output with VT100 compatible terminals.
Fixed logic with notification so that allow can actually remove i/o. Replaced messages in appserver, servermodule, and handler so that they are now using notification.dart.
