Winding down the "Incubator Repositories" program

[Gervase Markham]

We plan to wind down the Incubator Repositories program, as it's no
longer necessary.

Incubator repositories were set up to allow Mozilla people to
collaborate more easily with people from outside the core Mozilla
community who were not able to earn commit access.

However, the program has been overtaken (in a good way :-) by events.
Now the new Commit Access Policy is in place, it's very easy for
outsiders to get commit access to Hg user repositories - they just need
to be vouched for by one existing normal-level committer. This has led
to the type of work formerly done in incubator repositories being done
in user repos.[0] And if it's necessary to create a more complex repo
e.g. with build automation, it could be specially created and also
placed at Level 1 access, like user repos are.

So, we plan to wind it down by archiving the policy, placing an
"obsolete" note on it, and removing the Activities module. Obviously,
repositories created under the program will continue to exist and work
exactly as they do now. No technical changes are planned.
