Updated the bootstrap 2 template to 2.3.2 and font awesome 3.2.1

This updates the bootstrap template to Bootstrap 2.3.2 and Font Awesome 3.2.1. As with the previous template, glyphicons are not included. 

I also renamed the template bootstrap2 instead of just bootstrap. Since bootstrap 2 has better legacy browser compatibility than bootstrap 3, bootstrap 2 and 3 will probably continue to co-exist for at least a while, thus adding _2_ to the template name gives the flexibility to support both a bootstrap 2 and bootstrap 3 template.
