Fix firefox inability to set focus at beginning of line by adding height...

... to element.  Clean up implementation a little (phpstorm was complaining).   Remove profanity ;)

I did searching all over the net for something simple like this lib that aims at being sort of temp fix while contenteditable makes up their mind how it should be implemented.  I've worked many many hours trying to work with CKEditor, Aloha Editor, and started to see that what was needed was less,not more, especially for clean implantations.  I then did a quick try with Mercury.js, but to no avail.  I then saw this lib, but it didn't work for me in Firefox, I used my expertise in js to hone it a bit so that it would.  I think we may have a winner!
