Gizmo Daemon Code

Work on hotplugging, almost there, just need to figure out why
delete events show in the dev directory

Stop null events from sending
send full (raw) events to python

- More pythonification -- full C++ inheritance model now translating to python.
- Sending events to python

More pythonicification -- remove excessive arguments to
onQueryDeviceType

Much cleaner, can now just pass in a FileWatchee since it inherits
DeviceInfo

Device query types back from python fully working

Update PYTHONPATH to use mConfigDir (-c switch)

Fixups in the python / c++ interface
- using proper constructor (need to explicitly call constructor if the python's base class is a c++ class!)
- imports from inside python files now work (sys.path.insert being called before scripts executed)

Add a python interface for registering device types (GizmoDeviceType.py)

Register devices, call to python script to get device type
Switch from list to map where appropriate for more speed

Minor bug fixed in the event watcher (added inotify fd to poll list twice)
