MQ2Boxr: Support MuleAssist, remove campradius commands
Added support for MuleAssist
Removed the CampRadius
command. This concept is modelled differently
in the different combat assists, and mq2boxr will probably just cause confusion
by including it.
When debug logging is enabled, boxr will now log all commands it executes.
Refactored how the box adapter objects are managed, to make it easier to extend with new adapters.
