v1.1.1 Release

This release defaults MAVLink to on via USB and only offers the NSH shell via USB when the microSD card is not plugged into the autopilot.

A second huge addition is the support for log downloads through the specialised log protocol and QGroundControl (USB on any flight controller and Wifi on Pixracer are supported).

It also includes various smaller improvements and bugfixes for all airframes and boards.
