implement closing issues in commit messages
Currently, if I put "fixes #id" or "closes #id" into a commit message, redmine will generate links to and from the issue, but it will not automatically update the issue's status. According to http://www.redmine.org/projects/redmine/wiki/RedmineSettings#Referencing-issues-in-commit-messages , there should be an option for this to happen.
Ideally, "fixes" should set the status to "Resolved" and "closes" set the status to "Closed", but I gather that may not be possible, or may only be possible in newer versions of redmine. If they both need to be mapped to the same status, I think "Resolved" is the more appropriate choice.
