From ticket to wiki : add links to ticket/comment metadata when appropriate

[romain.dalverny@…]

In a ticket, we have several metadata that relates to something existing in the Trac system: milestone, component, etc.

It would be helpful to have these fields link to their actual wiki page (or to a template-based url, defined in the configuration file):

• the milestone field would redirect to the milestone page,
• the component would redirect to the component view in the milestone page,

Plus, in case these would exist as well in the near future:

• each keyword could redirect to a search page looking for every item with this keyword,
• each person (reporter, owner, on cc list, anyone who adds to the ticket) could redirect to a user page summarizing done and pending work in the whole Trac.

While not adding direct context to a ticket, it would make it easier to access data related to it, without a need for a manually typed search or several clicks.

Depending on how site-specific these semantics are (the user one for example), a plugin may make sense here.

The milestone and component links as described above are a must IMO.
Would be much appreciated if rescheduled to 0.11 ;) and maybe only solved for those two parts.

It's already the case for the milestone (see #449).
For the component, well, there's nothing to redirect to for now... that's why it's a 0.12 thing.
