Auto use Ruby version with gemset

To use a specific Ruby version with a gemset, create both .ruby-version and .ruby-gemset files in each project. (Adding these files to .gitignore is recommended!)

Example:

Inside .ruby-version, specify the Ruby version you would like to use for this project:

ruby-2.4.0

Inside .ruby-gemset, specify the name of the gemset you would like to use for this project:

depot

Creation of these file will be equivalent of using:

• rvm use ruby-2.4.0

• rvm gemset use depot
