Overhaul to SMOF for WordPress 3.8

Hi all, some major changes have been done to SMOF to support WordPress 3.8. The admin panel is fully responsive (because it utilizes the same DOM structure and CSS selectors as other elements). CodeMirror was also added for syntax highlighting for things like custom css and other code.

Additionally, these other changes have been done:

* Updated maskedInput
* Updated iris js/css
* Added CodeMirror 3.20
* Added version numbers to URI string
* Moved all scripts to the footer
* Cleaned up trailing spaces in all files
* Cleaned up code across SMOF so all code is consistent with each other
* Converted admin-style.css to `.scss` format with `compass`
* `functions.options-sample.php
