Since the Static const char * items are private and nothing
should access them besides the MainWindow class, declare
them inside of the .cpp file with static linkage, this way
a few good things happen: they are not exported as symbols
to any other class (not even with private linkage) and also
if we need to add a new one, on the .cpp, the only compiled
file will be the cpp, instead of the tons of files that include
mainwindow.h

If you choosed View->Fullscreen, the app would go to fullscreen,
but if you then go again to View->Fullscreen, the app would still
be fullscreen but the menu item would be unselected - leaving
UI and settings inconsistent.

qobject_cast doesn't use RTTI to figure out the type, it uses
an internally stored relationship, wich is much faster than
RTTI. I grepped the code for dynamic_cast and there are lots
besides this one, so I'll later try to figure out wich ones
are QObject inheritances and change acordingly.

The QString behaves faster if used with const - reference on
a QForeach.

if an unknown string was passed to createInnerDockidget,
the widget would not be created but a reference to the null
pointer would still be saved on the avaliable dock widgets,
and thus any code that foreached the list accessing methods
could led to a crash.

Since it's just a state-toogler, use the return value of the
method to set the values directly.

This is in preparation for full Qml main window

- Delete all old map code

- select active vehicle
- arm/disarm
- select flight mode

Also:
- Remove unused code

Too complicated supporting both modes as editor becomes more complex

These use OpenGL implementation which prevented moving to ANGLE
support. Since they are rarely used they are being remove instead of
being upgrade.

Plus lots of other cleanup

- MultiVehicleManager is a Qml friendly replacement for UASManager
- Vehicle is a replacement for both UAS and AutoPilotPlugin
