Pixelthing

Hi,

Here's a bit of a monster set of changes for your consideration. Main changes are:
- adds more access to the functionality through the config options
- changed the strength calculation formula to three regex tests (I'm not terribly good at regex, so they're largely googled and modified)
- added the option to auto add a wrapper to give similar look/feel as in flat UI Pro, but with the addition of icomoon icons.
- the show/hide can be config'd separately from the strength indicator

I've added it to a new branch to make life easier, and there's a demo on http://codepen.io/pixelthing/pen/zqHEC . Let me know if any of it is any help, or if you have any questions.

Thanks for the script - we're using it on our accounts system now!
Craig.
