This reverts commit d383692.
The CoffeeScript ruby library is no longer maintained. A new template implementation that uses supported CoffeeScript tools may be added in the future.
The MustacheTemplate implementation hasn't been right for some time and conflicts with the mustache/sinatra.rb extension library included with Mustache. Removing for 1.0. This template engine may be put back in the future if we can find a model that makes sense.
don't wear a stache
remove the ability to expose buffer as an arbitrarily named variable
