[PATCH] Add einstein.

Hello,

the attached patch adds a game the source code of which has almost
disappeared... So lots of annoying little things to change. I do it (mostly)
in a build phase right now; should I rather use a patch?

The one thing that bothers me is the lack of license: Debian claims it
is gpl2+ and included the package in previous editions; the source code itself
has no hint of a license, the website from archive.org speaks of "free cross-
platform open source" without further detail.

Actually Debian at
   http://metadata.ftp-master.debian.org/changelogs/main/e/einstein/unstable_copyright
also gives an author; so at some point in time in some galaxy, more information must
have been available...

There is actually more info in a Debian bug report!
   https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=289339
It points to the following page:
   http://www.babichev.info/en/projects/index.html
Looking at:
   http://web.archive.org/web/20150222180355/http://www.babichev.info/en/projects/index.html
"(...) Einstein (...)

Following the link leads to here:
   http://web.archive.org/web/20150221145051/http://www.gnu.org/licenses/gpl.html

So is this okay to include under gpl3+?
(In which case I would update the patch and also add a pointer to
   http://web.archive.org/web/20150222180355/http://www.babichev.info/en/projects/index.html).

Andreas
