Include gems with other name than repository

Use the correct path to a git dependency's source code:

[gem_home]/bundler/gems/name_of_gem
instead of:
[gem_home]/bundler/gems/[name_of_repo]

A gem has been added to the example project which has a another name than its repository. Please tell me if it seems unsuitable and I'll remove it from the PR.
"supports gems with names that are not the same as the repository they are installed from"
