Firmware Upgrade usability rework

Fit and finish

Conflicts:
	src/AutoPilotPlugins/PX4/AirframeComponent.qml

Increase timeouts for unit test runs in Team City

Also check for writable settings in unit test runes

Param read timeout too short

Airframe Config: No longer tries to reconnect after reboot

Was causing unnecessary read re-requests to get sent out

File Manager fixes and unit test

Don't delete link configuration if there is still an active link.

ViewWithDialog -> QGCView

- More more on making QGCView real
- Converted Parameter Editor to QGCView

Airframe config

Cleanup FileManager

- Download working again
- Fixed lots of bad error handling

New burst download for file transfer

Skipping DNS lookup if not needed.

Much better handling of missing parameters
