All ticket modifications should be tracked in timeline

[Mikael Hallendal]

It's currently next to impossible to track changes to tickets since you don't have either mail support or the possibility of showing it in the timeline.

If included, this should be configurable, since it will typically generate alot of events.
It is useful for some aspacts though, for instance the Timeline RSS feed.

Description by jamesm@…:

If any change is made to a ticket (new comment, etc) it should appear in the timeline.

Additionally, when tickets are modified (new comment, change in milestone, etc) the summary
should be displayed in the timeline just like when a new ticket is added.

This allows the timeline user to quickly filter the tickets of interest without having to
drill down into them to discover what they are about.

See dups #662 and #890, latter has a patch even.

This will be my first Component...
The feature is nearly ready, I still have to check how to
make it optional (according to [1584]).

[cboos]

Implemented in [1594].

Thanks to the new TracPluggableModules framework,
it is easy to make this feature optional:

It's in by default, but you can add it to the list of
disabled components in the trac.ini file:

[disabled_components]
Trac.Ticket.UpdateDetailsForTimeline = yes

[cboos]

Note that after the ticket module refactoring,
the correct way to disable this component is now:

[disabled_components]
trac.ticket.web_ui.UpdateDetailsForTimeline = yes

(TracIni was also updated with the correct name)

Just for people looking for this issue and seeing this ticket:

In current trac this option needs to be enabled by setting the option ticket_show_details in section timeline to yes.
