Release 0.7.8

Ruby upgrade to 2.0.0

Possibly required for deploy to production:

- upgrade rvm `$ rvm get stable`
- install ruby 2.0.0 `$ rvm install 2.0.0`
- install bundler `$ gem install bundler`
- install passenger `$ gem install passenger`
- `passenger_config --ruby`
- update the sapi file in /etc/nginx/sites-available/ to use the correct passenger include line

Possible issue: remove no_ruby_wrapper command from the ~/.gem file
