 * Idea loosely based on JASH, http://billyreisinger.com/jash/
 *
 * Website: http://gridder.andreehansson.se/
 *
 * Changelog:
 * - New GUI! The new GUI should be less obtrusive and has been repositioned.
 *   It is also featuring a slight delay on inputs so that you'll have a chance
 *   to change the settings before it is re-rendering the grid
 * - Due to a lot of inquries regarding affiliation with jQuery the filenames has
 *   been changed, I'm very sorry for the inconvenience!
 * - CSS issues with the GUI should also be fixed in more websites, please report
 *   in any issue you stumble upon
 * - A small bug in IE that made the paragraph lines not position correctly has been
 *   fixed
 * - A dropdown box has replaced the columns input box, 960 Gridder calculates the
 *   proper number of columns that can be used with the specified grid width
 * - The 960 Gridder is now displaying perfectly (into the very pixels) in all
 *   A-grade browsers (according to browsershots.org)
 * - An option to invert the gutters has been added, set this to 'true' if
 *   you want to use it, OR use the shortcut CTRL+ALT+A
 * - Some other minor changes...
