List of changes:
* Use 128 bit characteristic UUIDs when creating GATT table entries
* Change primary service attribute value to 128 bit custom service UUID
* Use raw advertisement data to convey flags and 128 bit primary service UUID
* Use raw scan response to send device name as complete local name
* Increase maximum device name length in relation to maximum scan response length
* Set Characteristic User Description attributes for each characteristic to convey protocomm endpoint names
This will be useful if a webserver is already running and the application
does not want protocomm to start a new instance.
