Import some, I think, interesting gnome shell extensions that
can be installed separately.

Also create a metapoort (gnome-shell-extra-extensions) to install
all of them in a row.

Add two more g-s extensions. I'm not including those into
the metaport, because I not sure those are not stable enough
or perhaps I did not know how to use them.

Use those at your own risk.
