AUI-1444 - Replace textboxlist-deprecated with token-input

Hi Maira,

Attached is an update for https://issues.liferay.com/browse/AUI-1444.

Most of the commits have been squashed into 1e669a1.  I also added a few more unit tests to bring up the coverage.  I'm not exactly sure what the percentage is but I would say around 90%.

Please let me know if there are any other issues.

Thanks!
