* Consumes new comments on JIRA issues.

* NOTE: In your JQL, try to optimize the query as much as possible! For example, the JIRA Toolkit Plugin includes a
// "Number of comments" custom field -- use '"Number of comments" > 0' in your query. Also try to minimize based on
// state (status=Open), increase the polling delay, etc. We have to do a separate query for *every single* resulting
* ticket in order to load its comments! For large organizations, the JIRA API can be significantly slow.
