JavaScript exception and minor UI tweaks.

Removing camera control experiment.

Turn off flick/pan gestures on map when follow vehicle set

Mission Item Status: Only 1 decimal place for values

Fix typo in brand image properties

Toolbar Indicators: Fix reference to non-existent property

OSX Installer: Bump stretch to try to get installer to work

Fix problems with core plugin virtually

Add support for MISSION_ITEM_INT

Allowing to skip going to the Summary page.

Core/Firmware plugin work

Fixed wing landing pattern fixes

Setup - Radio: Fix crash from bogus param values

Plan - Mission Item Editors: Clear current item before adding new one

Opacity tweaks to polygon editing

This closes out all value editing before the new item is added. Fixes
the bug where you enter a new altitude in last waypoint, don't press
enter and then add a new one. In that case altitude would be set after
new item was added. Hence it would not carry to new item.

More fun with FW landing pattern geometry

Should be all working now except for distance < radius cases.

PX4FirmwarePlugin: Rework flight mode override mechanism

Previous version would require plugin to override all the
isFooFlightMode methods to work correctly. Now just change mode name
and regular plugin code works correctly.
