Get rid of isAlwaysWatched

I assume this "isAlwaysWatched" just "happened":
We had notifications to talk page owners, probably because we didn't have
notifications based on watchlists yet. That probably grew into the "talk page is
always watched" - I guess. I definitely can't remember any discussion about
force-watching one's own talk page.

By default, a user watches his own talk page automatically. We should not force
that: if and should someone decide he wants to unwatchlist his own talk page, he
should be able to.

So, I'm removing isAlwaysWatched because I assume we never planned for this
"feature", it just happened as a result of how notifications & watchlist-based
notifications were built.

Move watch star for boards next to the header.

Currently requires star to be positioned scarily, but it does work,
and also on Mobile.
