Have only 1 new tab page max at any given time

[mp1982]

Sometimes it happens that I get 3+ new tab pages open for some reason.

I don't need that, likely most people don't either.

I would enable a flag to only allow 1 new tab page.

Opening another through click or ctrl+t should just focus that one.
