[Development] quickcontrols has now a hard dependancy on widgets.

[Gunnar Roth]

Hi,
Recently i deteced that quickcontrols plugim has started to add a hard dependency on widgets  ( on wec2013 and win32 at least ).
dpends.exe is showing

as imported functions from Widgets library.

In contrast to this the quickcontrols dialog plugin has  only a soft dependency via qpa, because of the possibility to use the widgets dialogs as a fallback.
Ir is very surprising to have a dependency on widgets, which loads this huge dll on our wec2013 platform into memory ( for performance reasons paging of exe/dll is switched off) . I admit that this does only happen if you also build widgets library, but i usually build as much a i can on a platform, even if i don't use it yet.
 
With this patch i now disable that dependency.

I would really appreciate a configure option for this.
