Title: [FIXED JENKINS-11759] Allow single user with multiple usernames, therefore allowing same person to be identified

This adds an option to global security settings that permits the definition of alternate commit names for Jenkins users. If you have user "john" committing from location one as "j.doe" and location two as "john.doe", it is now possible to prevent automatic new Jenkins user creation by mapping both of those commit names.
