[scribus] recalculation of overflow is not correct

Your script was not finished as it just attempted to add a single value 
to the height of the text frames.
I cleaned up and simplified the logic and here is a working version of 
your first draft for you to study and
continue to develop toward your goal. (You will probably want to use a 
while-loop testing OverFlowChar.)

For debugging, you cannot use print statements (you won't see them in 
Scribus), so it might be more useful to
insert scribus.messageBox() commands to see intermediate variables, etc.

Below, the script just adds 10 to the height (1,000 was way too big) and 
I have verified that
the script runs and performs as expected in Scribus 1.3.5svn.
