[Gnu-arch-users] Swap-mirrors update

[John Meinel]

I recently had a colleague who wanted to use an offline mirror. I found 
the "swap-mirrors" script in tlacontrib, but I noticed that it didn't 
handle signed archives.

So I went ahead and updated it. Attached is the patch. (Yeah, I could 
set up an arch repo, but it isn't worth it for this one change)

Basically, I just check to see if there is a signing rule for the 
"-SOURCE" repository, and move it around so that it stays the same (in 
case there is a custom rule)

Then I keep the -MIRROR always pointing at whatever -SOURCE is currently 
registered as, so tla archive-mirror should always work.

Also, small fix to set the default archive when not in a tree to the 
actual default archive.

Let me know if this makes it into tlacontrib so that I can just "tla 
replay" instead of keeping my own changes.
