Maxlength Added

I added the check for the maxlength and it is working well. It is also catching pasted content and limiting it to the  maxlength. I haven't looked at the _updateVal function yet for the autoFormatting fix. Sorry about that. I got distracted with a release at work. I'll try to get to that either this weekend or early next week, but I wanted to get this over to you while I was thinking about it.
