This reverts commit 8aa9f2cc07.
I agree with the following comment and as such have reverted the patch.
Quoting Phil Ringnalda <phil@chetcolibrary.org>:
Everything currently in the chunk labelled "Self Checkout" is
preferences used to control sco-main.pl, a feature that does checkout
and renewal, and optionally with the preference AllSelfCheckReturns,
also checkin.
Everything currently in the chunk labelled "Self check-in module" is
preferences used to control sci-main.pl, a separate feature that does
only checkin, and does checkin whether or not AllowSelfCheckReturns is
set.
I'd think a better solution would be to either rename the preference,
which is actually AllowReturnsInSelfCheckout, or rename the chunks to
make it more clear that they are preferences for two different features.
