[AD] New mailing list!

[SiegeLord <siegelordex@xxxxxxxxx>]

Hello folks,

So after a bit of searching for a new home for Allegro's mailing lists, 
I settled upon TuxFamily (https://www.tuxfamily.org/), a nice France 
based FOSS hosting site. It seems moderately active, and has some 
reasonably big projects hosted on it (e.g. Eigen). It's perhaps more 
active than GNA ever was.

The new mailing list address is allegro-developers@xxxxxxxxxxxxxxxxxx, 
courtesy of Elias's help. Hopefully if we ever move mailing lists again 
at least we won't have to change the address. You can sign up for it 
here: 
https://listengine.tuxfamily.org/lists.liballeg.org/allegro-developers/ 
(and please do, I think we might end up turning on moderation for 
non-members; it is open for now though).

(Actually, I could perhaps migrate people who are subscribed over at 
GNA.org, but perhaps this should be opt in? Either way, I don't have 
access to the GNA.org admin interface. Along the same lines, I probably 
can't close the GNA's mailing list, so we'll have to shepherd the 
stragglers over to TuxFamily).

Also, for the actual developers, it's probably a good idea to make an 
account at TuxFamily, in case there's any bus-related accidents.

Either way, they imported our archives so everything is in one place. 
It's not mailman anymore, but the software they use seems to do its job.

In terms of the rest of the stuff hosted on GNA (e.g. the downloads) 
some of it will be migrated over to TuxFamily, while the rest (the 
release archives/binaries) I'll probably move over to GitHub.
