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 current monitor used was the 'default' one, the primary monitor

like mine was for quite a bit, you'd spend like 20 minutes trying to
find the preferences dialog, like I did.

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.
