uncrustify selected text

Hi,

I've been using an automator action to uncrustify, but an Xcode plugin is way nicer.

I have an old Mac Pro I can't update to 10.8 and the uncrustify-binary you had included crashed for me on 10.7, so I've replaced it with one built from Macports, I've tested it on 10.7 and 10.8 (Xcode 4.6.1).

My old automator action worked by piping selected text so I've extended the plugin with a new menu item to uncrustify the current selection (multiple selection supported).

thanks!
