 Wrappers & Classes for interfacing with bluetooth via BlueZ 5 from Mono via DBus
 
 Uses a patched dbus-sharp for dbus calls that fixes properties, as well as allowing receive for unix file descriptors via socket control messages.  Support for socket control messages come from using a patched mono build.....  so yeah, this is a pain to set up right now, hopefully once these changes get packaged up for mono and dbus-sharp this will be much easier to use.
