New Revision: 16681

URL: http://svn.gna.org/viewcvs/relax?rev=16681&view=rev
Log:
Added support for the user function arg type 'force flag' to the GUI user 
functions.

This arg type will, in the GUI, always return True.  This is because a user 
clicking on 'Ok' or
'Apply' is essentially saying that this operation should be performed.  The 
special Force_true class
was created for these arguments which simply ignores SetValue() calls and 
always returns True from
GetValue() calls.
