Bug#958853: Fix

[Drew Stephens]

I managed to get 2.1.15 from the package working for now for putting 
int(round()) around numbers in preferences.py and deckconf.py when they 
were returning the unexpected float type error. For some reason, even 
though it says the package is removed from testing, I am still able to 
install the package from the repositories.
