Apply 100% width to Chosens added dynamically

When clicking the "Insert Download" button in the WordPress for an editor that is dynamically added to the edit screen, the select box is broken because the CSS fix is not applied to the select box. This issue is caused by the event being improperly delegated. By binding the event to `#post`, it will be applied to WordPress editors that are added dynamically.

Additionally, the `$('#choose-download .edd-select-chosen')` is an inefficient selector and has been improved (test http://jsperf.com/jquery-selector-race).

Purchase button in checkout needed a more targeted jquery specifier to change its text back from Please wait... to Purchase.
Before, if there was an error in the purchase form, the Apply button (for discount codes) and any Login button would also change their text to 'Purchase'! They still worked fine, but the text was wrong - up to three buttons on the page all said 'Purchase' at that point.
