Activity Stream moves into Firefox (and mozilla-central)

Hi,
This morning I've disabled the Activity Stream project in Pontoon. Strings
are now part of the Firefox project, and are stored in mozilla-central
https://hg.mozilla.org/l10n/gecko-strings/file/default/browser/chrome/browser/activity-stream/newtab.properties

History has been imported as part of the migration, in both Mercurial and
Pontoon. For that reason, if your locale had pending suggestions for
Activity Stream, those should still be there.

There is still a delay between strings landing in mercurial and becoming
part of Firefox builds. That should be solved in the coming months, when
building Activity Stream will become part of Firefox build, and not a
separate process.
