Use ExpandingTextareas plugin over the dated Elastic

[waynehoover]

Hello,

Thanks for this fork. Thought you might be interested in using the excellent ExpandingTextareas plugin over the elastic. Elastic had some hacks and always gave weird results when I tried to do the most basic of styling to my textarea. (ExpandingTextareas)[https://github.com/bgrins/ExpandingTextareas] is based on an excellent article on AListApart about expanding textareas, and works like a charm every time. Its also maintained, which is why I submit this patch to your repo and not upstream to podio :)

I included the lib as a submodule, because hey its more fun that way :) I also updated the index.html in the docs.

Thanks for the pull, Wayne. I'm going to try it out on our staging server before merging it in, since I try to keep this fork in sync with our site - but looks great on the demo html. I know we've had trouble with the elastic plugin before.

Hmm, looks like the new plugin doesn't always preserve CSS like it is supposed to (loses my min-height property). Seems weird since there's a test case for that in their demo. I'll have to look and see if it's some combination of styles that break it.
