Feature/bootstrap less

I had previously submitted a merge request on master. I made some more modifications to restore some changes from the develop branch that I had overwritten. Besides some other small tweaks everything else is the same as before. Implementation of Twitter/Bootstrap and bootstrap.less using LessPHP. At the least this ensures that they are getting the latest version of Twitter Bootstrap. This also allows them to extend using the LESS mixins. Let me know if you are interested in merging this.
