Joystick: update gui and send new mavlink target messages

Mavlink update

More FTP support, plus unit tests

Added:
- sequence numbers
- better filtering for image encapsulated data messages versus FTP
- directory list now contains file sizes
- open command now returns file size in data

Run macdeployqt from same dir as qmake

Handles case where multiple versions of QT are installed on machine.

Fix various styling issues

Also added a corresponding style for the light themes to make it a little prettier (though it wasn't broken on light themes).

Added all perspectives to advanced menu and rearranged items.

Tried to order items in order of importance.
Also all perspectives now have their own shortcuts.

Remove unconnected view from QGC.

Conflicts:
	src/ui/MainWindow.cc

Finish removing MAVLink generation code.

Conflicts:
	src/ui/MainWindow.cc

Both on the backend (replaced with DEFAULT view) and on the front end (removing UI menu items).

Removed all dead code from MainWindow.

Includes removing an if-statement that should've been dead but was erronously applied to the following statement. Dead code = bad, if-statements without braces = bad.

This was deprecated on Febuary 3rd, 2014 and removed a little later. This finally completes that process.

Simulation button should be checkable

Without this, when you go to airframe config and the current config is
Simulation it will not be selected. Hence you won’t know what the
current config is.
