Add regexps to parse more SCM messages
We are using commit messages like
feature/#ID_sometext where ID is a Redmine issue ID.
Currently Redmine does not add commits with such messages to the associted revisions because of the
/ before the #ID.
Also these strings will not have a clickable link to the issue id because the the
_ behind the #ID.
With this patch Redmine will add such commits to an issues revisions and also the #ID in the message will become a clickable link.
