Merge pull request #4 from nqrduck/get-device-list

Bump version and add device listing.

Tested with LimeSDR USB and LimeSDR Mini  2.0 connected  to one PC. Devices could be retrieved using the get_devices_list()  method. The  active  device could  be  changed using the device  property of the PyLimeConfig object.
