appserver can now service requests to the root page.
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.
