(GitTools#89) Add required mappings for GitLab models

During testing, it was found that release notes containing contributors
could not be created, since there was an exception thrown when trying
to map models.  Digging into the problem, there were some missing
mappings, and also some required translations between properties with
different names.

Once these addition mappings were in place, it was possible to create
release notes, with contributors, in both GitHub and GitLab.
