Simpler control design for better mobile display

This forces a commit on any uncommitted TextFields

Android done.

UI Tweaks for all mobile platforms.

Was causing layout issues between mobile and desktop. Couldn’t get a
good looking layout to work on both.

Made then the same size of toolbar cell height

Everything is now based off of default font pixel size

Use default font wherever possible. Where that doesn’t work, use
ScreenTools::dpiAdjustPointSize.

Controls respect QGCPalette settings. Also added test window.
