The `RoutingPortCollection` type appears to not be currently
serializable. If a class that contains this collection is going to be
serialized, the collection should have the `JsonIgnore` attribute added.
If the list is needed, use a conversion object and convert it to a
regular list.
In order to solve some dependency issues that keep cropping up, MC
should be moved back into the Essentials repo and loaded automatically
on startup. This will allow for all plugins that use the MC Messengers
library to use the same version without fear of overwriting a dll due to
loading of plugin libraries.
