Merge pull request #13 from mboynes/master

Updating chosen implementation to work with dynamically generated elements
Fixing syntax error for "on" event for chosen selects
Updated Fieldmanager_Options to always run get_taxonomy_data for non-preloaded fields to solve an issue with repeating fields inheriting the empty data set of the prototype
hidden element for grid renumber issue
Optimizing get_form_name: Using the speedier foreach instead of a for loop, removing count() calls
Adding catch for save filter to only continue if $_POST['post_type'] is set and we're not doing an autosave

This was throwing a PHP notice for every known field in a site on any "new post" page. If a site has a total of 200 fields across 20 post types, it was throwing 200 PHP notices any time you went to create a new post of any post type.
Ignoring DS_Store files
