This has been long overdue: pretending that "http server"
is an Apache2 with PHP5 was wrong for ages, and providing
apache2/nginx, php5/php7 choice along with more databases
was waiting for its user proposal.

Follow these changes in server feature as well.

Thanks snejok@ for providing this one.

Make it prefix not suffix so that sorting order
in alterator-pkg is natural instead of chaotic
during installation; turn some implicit "tools"
into explicit ones for consistency either.
