Update to Bootstrap 3.0

I updated my repository bootswatch-scss to match the bootswatch/bootstrap 3.0.0 changes. It was originally based off the files from this repo.

I don't know if you'll want to accept this pull-request sight unseen, as you made notes to the custom conversion scripts you've made. You may want to check out my repo to see how I generated these, there were only a handful of manual updates that needed to be made after I converted them using grunt.

This is related to issue #47
