Allow entering of "123" zoom instead of only "123%". Previously, if it couldn't find a % to chop, it would kill the last digit (the '3' in "123", giving an incorrect, 12%).

Add hack to get around "10&0%" action text which sometimes happens with kdelibs4.

okular developers: after updating kdelibs, zooming should work perfectly - please let me know if it doesn't.
