Quick regenerator of zproject templates as used by 42ity ecosystem workflow,
including removal of CMake recipes we do not use in our common components
(see --kill-cmake|--keep-cmake for definitive behavior).
After the job is done, it verifies the recipes by running autogen, and then
starts "git difftool" and "git status" so you can revise the templated changes
The "gsl" tool should be installed (from zeromq repo, not older imatix one).

By default uses the currently checked-out workspace under FTY dispatcher repo
if present, or the system installation if used as a standalone script; also
can use another (-d) or even update the system installation (see -r vs. -q)
if your "sudo" setup permits that; and to use the current system installation
of zproject pass the -d " " option. You can pre-export a ZPROJECT_SRC value
in your shell profile, to use some custom path or the system installation.

To update a Jenkinsfile (not overwritten by default) use -J
To update a .travis.yml (not overwritten by default) use -T
To update git/IDE/clang configs (not overwritten by default) use -G
Update all files above with -A
