Should we keep xlife?

[Peter De Wachter]

Hi Barry,

You adopted xlife for the team a while ago, but I was wondering it's
worth keeping.

I was working on xlife 5.3 (which fixes #196498) a while ago, when I
learned about golly. And golly in my opinion away pretty much blows
xlife away. It has a modern user interface, uses a much faster algorithm
and is actively maintained upstream. (Try loading the breeder.lif
pattern, turn on the hashing & hyperspeed options, and watch it go :)

Given that xlife is ancient, unmaintained, unpopular and buggy, I see
no reason not to remove it.

(OTOH, if you disagree, the 5.3 version is pretty much ready to
upload. :)
