Remove excessive door management config variables

Too many config variables made this unnecessarily complicated. Most
servers will want the defaults. For those that want to customize further
they can easily overwrite these files.

These seem like the most logical defaults to me. Allow all of these
people to manage and unlock by default:
- door owner
- plot owner
- plot friend
- plot admin
- door friend
- door admin

Door friends should be able to manage by default so they don't have to
wait for the owner to come back online to add someone as a door friend.

Plot friends and plot admins can get around the door by removing it and
building another one anyway, so locking them out is pointless. It is
still useful to have these as separate variables for servers that do not
require plot poles though.

Regular friendlies should not be included by default, since we have the
more fine grained plot friends and door friends lists for that. Regular
friendlies will probably be replaced by groups in the near future
anyway.

Please post a comment if there are any issues with these defaults I'm
forgetting. Thanks.
