Provide autocomplete pieforms elements

[Aaron Wells]

The interface for artefact-level sharing ( https://bugs.launchpad.net/mahara/+bug/1298646 ) requires a Pieform element that will do AJAX-based autocomplete. You start typing in the name of the person you want to share with, and it presents you with a list of eligible people.

This functionality could also be useful in other places throughout Mahara as well.

There's a patch for this here: https://reviews.mahara.org/3260

It uses the JQuery Tokeninput library: http://loopj.com/jquery-tokeninput/

However, I think the JQuery Select2 library may be a better choice. That's what we use in Catalyst's internal issue tracking site, so I can vouch that it does a solid job. http://ivaynberg.github.io/select2/

I ran tokeninput and select2 by Julius for accessibility testing and he said select2 is better for accessibility as well.

I've attached a zip file containing the PHP files that I used to test this during development:

1. test.php: This is a basic Mahara page with a Pieform in it that has an autocomplete element.
2. testajax.php: This is the ajax script that supplies it with data
3. test.tpl: This is the dwoo template for test.php. It should be copied to theme/raw/templates/test.tpl
