Added project template

The compiled version of Twitter Bootstrap can be added to a new project simply by going to New Project... -> Web Project -> Twitter Bootstrap

Two things:
a. Not familiar with how IDs in Aptana Ruble programming work. I used com.aptana.project.template.web.twitterbootstrap, but this is probably wrong (I.e., it uses the 1st party "com.aptana.*" namespace.). You may wish to amend this.

b. The icon being pulled looks a little bit off, probably because it's originally 200x200 and not 48x48 as requested. You may wish to update the path with a properly-sized one added locally.
