porthole 0.99.4

Porthole is a ripoff of Mustache. It replaces the use of {{ }} with %% %%, because god hates me. I removed the Mustache authors from the list of authors, as I don't want to associate their names with this project. You can find the *real* list of authors by viewing the Ruby Gem "mustache" or by going to: http://github.com/defunkt/mustache
