Link Git committer/author to Trac users
|Reported by:||shogsbro||Owned by:||hvr|
GitPlugin currently returns the full name and email from the author/committer field, which is often much longer than the username setup within Trac.
Suggest making a lookup of author/committer email address against the Trac user database, and using the Trac username instead if found. If not there, show the current style author/committer.
