[vtkusers] Adding a text widget into qvtk

[Rodrigo Lovera]

hmnn it seems to be im too noob, solve the conversion problem with a
.toAscii

But definetely I'd like to know more about the interaction that these
textwidget could have, like I wrote before, to drag the text wherever I
want and things like that.

Thanx for your help
