#561726 by effulgentsia, TwoD, and sun: Make ajax.js and tabledrag.js implement Drupal.detachBehaviors().

- Patch #444344 by kkaefer, sun, Rob Loach: this change introduces a jQuery .once() method which streamlines the way behavior functions work. Previously, we had to manually ensure that an element is only initialized once. Usually, this happens by adding classes and selecting only those elements which do not have that class. However, this process can be separated out into a jQuery ‘filtering’ function which does all the grunt work.

- Patch #216904 by pwolanin et al: if there are more than 21 menu items under a parent, the weights got screwy.
