Notifications fixed to be compatible with api15
Running MedtronicCnlService.doReadAndUpload from UI thread

Fix #16 - show registered USB sticks in the registration activity
Fix #14 - show successfully registered devices after CareLink login.

Make only the log part of the UI scrolls.

Add comms retries when entering control mode, to handle the scenario where the app is launched with the plugging in of the USB stick.

Fix #6

- Refactor MedtronicNG class names
- Add support for uploading Pump status to Nightscout (pump battery, IOB, reservoir level)

Remove hardcoded keys.

Removed all options to use Dexcom or Medtronic CGM (sorry arbox0).
