CiUI 0.3

This is a development code base for CiUI. All bug fixes, features and patches will first be checked in here before releasing it as a version to clientsides repository.
CiUI is an alternate solution to iUI. It is built on the same principles as iUI with a few key differences:
- AJAX calls are performed after a page slides.
- DOM doesnt get overloaded with "pages" as they load. Instead, two DIVs are constantly being reused.
- CiUI sets the page titles on the source page and not on the destination page.
- Only specified "a" tags are assumed a part of the UI.

System requirements:
- iPhone or iPod Touch.

Enhancements
- The cancel function now functions properly (ciUI.cancel()) when youre trying to cancel a loading page.
- When a new page is requested while the current one is still loading, the current page will stop loading before trying to load the new one. (This was causing unexpected content appear after users navigated away from a page).
- Fixed an issue with the back button where it would sometimes be disabled when trying to get to the very first page in the hierarchy.
- Checkboxes return correct values in Firefox.
