Make maintenance mode a variable instead of a config. Then create

links on the Admin > Maintenance page to allow you to turn it on and
off.  This should be efficient since we cache all vars and look them
up on every request anyway.

This also allows us to have the Fix task enable maintenance mode while
it's running which greatly reduces the chances that somebody will come
along and hork the database while we're tinkering with MPTT pointers.

Fixes ticket #1259.
