Any mention of Issues, MergeRequests, or Commits via GitLab-flavored markdown
references in descriptions, titles, or attached Notes creates a back-reference
Note that links to the original referencer. Furthermore, pushing commits with
commit messages that match a (configurable) regexp to a project's default
branch will close any issues mentioned by GFM in the matched closing phrase.
If accepting a merge request would close any Issues in this way, a banner is
appended to the merge request's main panel to indicate this.

Also specify separate project factory for project with filled repo

Add Repository model to proxy request to Gitlab::Git::Repositoty and decorate commits with Commit model

Use existing methods for branch names: Ex use @repository.branch_names instead of @repository.heads.map(&:name)

This reverts commit 4524ba20.
