cc only on substantial changes

[fumanchu@…]

We've started using Trac for generic project management at my company. I've got several custom fields for tracking hours worked, estimates, cost, etc. These all work great.

Partly due to the number of custom fields, some of my users have complained that the number of emails being sent from Trac is overwhelming, to the point of "boy who cried wolf" syndrome; that is, they're being deleted without being read. I think the majority of that complaint can be resolved in my case by sending notifications to names in the CC list only if the ticket.get_changelog() contains 'comment' or 'description' changes. The owner and reporter will still be notified on all changes.

Patch attached which uses a config entry to accomplish this.

Notify cc recipients only on certain field changes

[Emmanuel Blot]

If you want to submit patches, please submit them against the trunk​ if the patch is about a new feature.
The branches/0.9-stable​ development branch is for bug fixing only, and won't support new feature.

Unfortunetaly, the notification code has been somewhat reworked from 0.9 to 0.10, so there are few chances the patch can be integrated into the current code base.

Looks like a duplicate of #2073 and #4056.
