Work around android Qt bug where wrong virtual keyboard is displayed

This is in addition to the existing text edit control.

Includes support for battery 2 setup

Adding missing qgcView to QGCMapPolygonVisuals instance in SurveyMapVisual.qml

Changed (selected) mission item color to primaryButton instead of buttonHighlight
Adjusted some colors for better contrast
Removed a few JavaScript exceptions caused by the order of object destruction

Some android versions leave a focus arrow indicator turd in the
control. This gets rid of it.

Convert bool settings to SettingsFact

Causing data loss

Doesn’t have a done key which doesn’t work with our user model. May
find a better fix later.
