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.

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.

There were two problems:
- the latest pgsql related groups made installation
  impossible (yes, that last minute change);
- hardware testing shows that use/stage2/kms is now
  requisite as xorg-drv-fbdev might just refuse to work
  with what looks like a perfectly good framebuffer...

Do away with them *quick*.

Pg 9.5 is the current stable version
while 9.4-1C is the current version
patched to run 1C Enterprise.
