function magic_extension_assets_theme_settings_form_submit in Magic 7

Submit handler for the theme settings form.

This form will take the theme settings, and for the css and js excludes, create the regex that will be required to remove the css and js files at will. It will then selectively clear the caches for those specific cache items.
