improve admin interface for components

[charlie]

While John's Javascript allows sub-components for ticket submission, it does not help component management. The component management page could quickly become fairly unmanageable as a result. The relationship should be in the database - this reduce the need for Javascript to only those situations where it really helps users.

There should also be a relationship between component and version.

Yes, that would be ideal, but as I said, I definitely want to use an official Trac install for this. We should not maintain the source ourselves (as far as possible). If you can do this with the official source I'm not against it.

An alternative "hack" would be to add a "Rename Parent:" [...] "to:" [...] form that renames everything matching "<parent>/*" and also "<parent>". It's not very nice, but it would do the job (and that without a lot of work on our side).

Or we can add a checkbox "Rename Children" next to the component's "Name" field (in component details in admin interface), so when you rename the parent you can easily rename all children, too (matching <Name>/*). What do you think?

Now it's possible to rename subcomponents together with the parent. This should be good enough.
