Initial commit to enable comment regex specification so that comments can trigger a build. To configure the comment regex, add the following to the job's config.xml:
      <triggerOnEvents>
        <com.sonyericsson.hudson.plugins.gerrit.trigger.hudsontrigger.events.PluginPatchsetCreatedEvent/>
        <com.sonyericsson.hudson.plugins.gerrit.trigger.hudsontrigger.events.PluginCommentAddedEvent>
          <verdictCategory>CRVW</verdictCategory>
          <commentAddedTriggerApprovalValue>0</commentAddedTriggerApprovalValue>
          <commentPattern>re(check|verify) no bug|bug.*</commentPattern> <!-- specify regex here -->
        </com.sonyericsson.hudson.plugins.gerrit.trigger.hudsontrigger.events.PluginCommentAddedEvent>
      </triggerOnEvents>
