Screen locks when user first moves pointer (hits keyboard) after returning to computer.

Version-Release number of selected component (if applicable):
spice-client-0.7.1-1.el6.i686

How reproducible:
always

Steps to Reproduce:
1. let spicec grab focus
2. leave computer for time when screensaver should kick in
3. move pointer or hit any key
  
Actual results:
screensaver kicks in instantly

- don't do anything with screensaver so it normally starts after it's timeout passes
- inhibit screensaver like media players do, resetting screensaver timeout when it releases pointer or loses focus
