Last Pre-release before 1.0 re-factor

Got rid of hard coding the D-Bus subscription, now the agent library exposes a new function for the actual agent script to choose what D-Bus interfaces it wishes to grab signals from. Refer to README for more information.

Will be re-factoring completely to make whole codebase more coherent and implement a file storage system for agents and a key,value store for better system persistence. Will also include more error checking and also try to include an environment simulator.
