title: Restricting Subversion commits if the Jira Issue key is Not in the commit message
body: <p>I am using SVN-1.7.4 for revision control and atlassian JIRA as the issue tracker for my LAMP website. I want to restrict SVN commit if any of my team member commits without mentioning the Jira Issue key for the same.
  I am using JIRA standalone and have installed it on my server. Google search gave me Subversion Jira Plugin (https://studio.plugins.atlassian.com/wiki/display/SVN/Subversion+JIRA+plugin) but it can only help me out in tracking the commits that had a JIRA key, not in restricting them.
  Please let me know, if I should post any more specifics about the issue. </p>
