"Clear/Refresh Cache" Button and control panel

CS-Cart needs some way for the administrators to clear the template and skin_repository cache by the click of a button. I made some changes to a template and while most templates changes will appear fairly quickly the coresponding images don’t always seem to refresh in the same timely manner. This can get problematic when one is trying to get things looking right or when making urgent graphical information changes on a site.

Please consider this for one of the future imporvents:confused.
