Get rid of most variable definitions in variables.inc.php

variables.inc.php is an old hack to save having to declare variables
before using them in pages.

Lots of the variables there are unused (leftovers from the old
create-*.php or edit-*.php scripts) or properly initialized in the file
using them, so there's no need to keep them in variables.inc.php.

The remaining variables in this file should also be dropped after
further investigation.
