savannah => trac import should be fixed

[ossi]

the ticket migration from savannah was "somewhat suboptimal", causing two practical problems:

• user names were lost, which makes the user-bound trac ticket queries mostly useless for the old tickets
• the comment trails are a complete mess, which makes them hard to follow

both of these problems are reasonably easy to fix retroactively.
i'd even do it myself if you gave me the rights to edit tickets freely.
(and with a dump of the database schema and contents, i could even make a perfect migration, but that seems like overkill.)

Replying to ossi:

You have TICKET_ADMIN permissions now.

ok, i think i've done it. i hope i didn't screw up too many ticktes - i didn't verify every single one with the same thoroughness.

i left the tickets with reporter "None" with slava. i presume he doesn't mind.
we can still fix it, of course.

as i was at it, i also deleted all test tickets from the mail2trac tests, and the three tickets marked as *** TRASH *** - i think they really didn't add that much value to the database.

for completeness, here's the script i used for the comment trail conversion.

Thanks for a great work!

I've fixed some fields of modified tickets (state "no branch" -> "merged").
