Option to sort topics alphabetically

I want to suggest a feature request, available to administrators, under Administration > Forums > Edit forum > Edit forum details, under 'Sort topics by' to allow forum topics to be sorted alphabetically. 

Presently 'Last post' or 'Topic start' are the only sort options available for topics - ie the sort order options are only chronological.

This is not very useful if you want to create a forum that is (for example) in the format of a noticeboard, where you want to list topics where chronology isn't important - eg such a topic list may be a student forum where the individual topics look like:

- Class lists
- New students
- Timetables

or an administration forum where the topics may be:

- FAQ
- Security: access control guidelines
- Security: using strong passwords
- What not to do on this forum

or a topic listing of bands under a 'Favorite Bands' forum:

- Beatles
- Klaus Wunderlich
- Nirvana

etc etc etc.

At the moment punBB can't do this for topics, and I think it would be generally very useful if it could.

I am encouraged that as a result of a previous feature request:
http://punbb.org/forums/viewtopic.php?pid=43318#p43318
Rickard amended punBB to allow alpha sort order for the Styles listed in the Profiles > Display drop-down in profile.php.

I think the option to alpha sort topics would be even more useful than sorting the list of styles alphabetically

Alpha sorting of topics has been raised as a modification before - http://punbb.org/forums/viewtopic.php?id=9049 - but it would be optimal if it were built into admin_forums.php as an option per forum out of the box, rather than as a hack.
