Add the necessary files to make publishable as a gem. This is maybe a little kludgy and I don't know if tehre's a better way to do it: because the original fork has the files laid out differently than rails gems, need, in the .gemspec file I create the needed folders and copy the js & css to them. There's no way to clean that up, though, but I have added those to the .gitignore. Fixes #80.

@danielfarrell : I had published my previous version to rubygems.org. Want me to do so with this one as well, or do you want your name attached to it there?

And apologies for doing this pull request off of master. Want me to move it to a branch and re-do?

We'll probably do this, but it will end up being in it's own repo. I'll close one it's done.
