- Patch #172755 by c960657, klausi: autocomplete triggered when switching fields, 'undefined' written to field.

- Patch #444344 by kkaefer, sun, Rob Loach: this change introduces a jQuery .once() method which streamlines the way behavior functions work.

However, this process can be separated out into a jQuery ‘filtering’ function which does all the grunt work.
