Move mailing list archives to Google Groups

[bstrie]

Google Groups makes it nicer to browse archived threads compared to what Pipermail currently offers. The dev-servo mailing list already does this (note the archive link at https://lists.mozilla.org/listinfo/dev-servo ). I hear that a lot of other Mozilla mailing lists do this as well.

I've recently discovered that rust-dev is mirrored to Gmane:

http://thread.gmane.org/gmane.comp.lang.rust.devel/

...which doesn't provide the commenting facilities of Google Groups, but at least now browsing and searching is possible. Closing this.
