The redundant bincoming and iincoming were added by me in ck9 to solve
this problem with preferences in general. NCSA never finished the code
that hooked up reading the preferences file to actually storing prefs in
memory, so when I turned it on, everything dereferenced a null pointer
and crashed. I added the redundant arguments so that for simple prefs a
simple value could be passed along directly (strings still need a pointer
of course) and there would be no messy mucking around, but I only did this
for the ones I needed to get running. Obviously I missed one, and I should
just do the rest of them for ck10 at the same time.
