Fixed orbit SlideAnimation
The animation was using animate({margin: '0%'}) which would effectively animate the css margin property.
The intention was to animate the marginLeft or marginRight property (depending on ltr or rtl of document).
Fixed performance of forms refresh_custom_select
refresh_custom_select was looping twice thru the select options:
- once using $() to create the li elements
- then a second time trying to find the selected and disabled elements

this was causing the page to freeze when selects with many options were refreshed
instead the code was changed to construct the list's HTML with a string, and add
the selected and disabled classes at the same time if necessary.
fix abide sample
Fix "close" event for Reveal

Currently the "close" event is not being fired when the user clicks the
modal backdrop with closeOnBackgroundClick true, since the close event
is being triggered on the closest .reveal-modal parent of the target.
This naturally doesn't exist when the target is the backdrop.
Corrected typo on Orbit page.
