Update README for QLoggingCategory usage

Flight mode setup

Place this file in the location specified here:
http://qt-project.org/doc/qt-5/qloggingcategory.html

This allows unit tests to simulate user selections in a combo box

Remove multiple overrides of activeUASSet signal

This allows use of compile time Object::connect syntax

Enlarge the perspective buttons on the toolbar.

Fly was way too small and Plan needed to be a tad bigger as well.

Unit Tests run from there own QSettings space

This is done by tweaking the application name when running unit test

Bumped developer version

Update for 32 bit Google earth information

Developer at 2.3.

Work around qRegisterMetaType race condition

There appears to be a threading issue in qRegisterMetaType which can
cause it to throw a qWarning about duplicate type converters. This is
caused by a race condition in the Qt code. Still working with them on
tracking down the bug. For now we register the type which is giving us
problems here while we only have the main thread. That should prevent
it from hitting the race condition later on in the code.
