Review request for KStars and Rafal Kulaga.


Repository: kstars


Description
-------

Currently zoom in/out factor is set constant which is very small so zoom in/out works very slowly, i.e. user have to keep rolling mouse wheel for long to get zoom enough to observe single planet. 

This features allows user to do quick zoom in/out by pressing ctrl + wheel/+-keys.
