Convert pTemplates into Smarty Templates

[zpin]

Ok, this would be a quick change, though. In the mean time I think I checked all the .php/.tpl files at least I haven't found any fatal errors on any of the pages anymore. Also I checked most of the basic functionality.

Here's the latest patch. It applies to the latest trunk (r3348). I ask everyone who can and wants to to test it and the ispCP devs to evaluate integrating it into the trunk.

Also, HenrikS contacted me about the new theme. He's currently implementing it with the new smarty templates but could need some help since he doesn't have a lot of time. Anyone who would be up for that can contact him directly or post here.
