Change "realfull" to activate everything

Change "realfull" to activate everything. After investigation, it seems that
having "realfull" not activate everything was a historical oddity due to
proximity with "full", not a goal in itself.

This changes the output of `scripts/config.py realfull`: now all non-boolean
options are uncommented.
