Add a pre-handler that triggers an input event when text is pasted into

Browse Source 
an xforms text input widget.
Use this in the Preamble dialog.

If anybody wants to help add this functionality to the rest of the dialogs
then feel free. Apart from FormPreferences (which has it's own prehandler
already that would need to be modified) there are about 60 text input
widgets that all need the extra code:
	extern "C" int C_CutandPastePH(FL_OBJECT *, int, FL_Coord, FL_Coord,
				       int, void *);

	fl_set_object_prehandler(widget, C_CutandPastePH);

Not too hard, is it?

* FormBase.C (C_CutandPastePH): new function that can be used as a
pre-handler to any xforms text input widget. Will trigger an event on
pasting into the widget using the middle mouse button.
* FormPreamble.C (build): use this pre-handler for the input widget.
