kjsembed uses both QUiLoader and QFormBuilder

[Erik L. Bunce]

I haven't seen this link problem on Mac OS X, however I agree we should 
probably default to only using QUiLoader.  I'll probably commit an 
initial form of that change today. 

I also believe we should move the use of QUiLoader out of the QWidget 
binding and into its own.  When I finish adding runtime loadable binding 
support I will probably have QUiLoader and QFormBuilder available as 
separately loadable bindings.  That way things that want to embed 
designer can still avail themselves of the QFormBuilder binding.

Thanks and Enjoy,
Erik
