#3811 balance readers db-choosing issue

[shane]

the balance_readers.pl script in themes/slashcode/tasks is ignoring a db's
active/inactive (ie 'isalive') status when it's doing it's thing.

it should take this into consideration, and only attempt to balance readers
which are active. otherwise, it throws errors in slashd and then other
tasks are not happy.

patch to fix:
