New Template Icons

Updated the template icons to higher resolutions, polished some of the icons, new icons for other templates. Looks much better now. Let me know if you find anything that needs fixing before this can be merged, or if you like it. 

I also cleaned up some of the code to make it a little easier to read (ex. capitalization, grammar, indenting, etc.).

Awesome project! Can't wait to see more (and hoping for an iOS 7 jailbreak soon)!
