Heroku Buildpack Ruby Version

This buildpack will read the ruby version from the project's .ruby-version file and inject that version into the Gemfile as an argument for the ruby method. This way the ruby binaries installations are delegated to the heroku-buildpack-ruby.

It also revolve ruby versions without the patch version or aliases. For example:

#.ruby-version
2.2

The buildpack will inject a full version into the Gemfile.

# Buildpack output
-----> Getting ruby version from .ruby-version file
-----> Found Ruby version: 2.2
-----> Adding Ruby version to Gemfile: 2.2.4
