Using MacRuby

Hey!

I noticed rb-appscript is not supported anymore, it says so in [their page]( http://appscript.sourceforge.net/rb-appscript/).

Because of this, the background changer wouldn't work on Mountain Lion.

So I made a version that uses MacRuby instead, with a great help from [this gist]( https://gist.github.com/jerodsanto/1229361).

It now works on Mountain Lion. I hope you like it.

Thanks for this nice tool! Will be very important for me on my current project. :)
