Link commits with Issue-System (Jira/Github/BitBucket) #48
Description
If we migrate a RTC project with WorkItems and source code with rtc2jira and rtc2git we would like to maintain existing connections between commits and WorkItems.
In RTC it was possible to assign workitems to changesets and these connection we should keep.
If we have a commit-message on git with a certain pattern (NUMBER: WorkitemDescription), we can add a prefix so that the commits targets the new system.
Due the fact that we keep the same numbers on both systems, a prefix is sufficient and there isnt any need for having a conversion table (oldnumber to newnumber).
