Subject: [PATCH] src/init.c: bail out if skin_name or font_name is "". Fixes a
 crash on AROS

src/filesel.c: fixed BSTR conversion routine for AROS.
Without this fix "RAM DISK" was printed as "AM DISK" in
the file selector.

src/setup.c: removed slash to avoid that paths like
"PROGDIR:/share" are created on AROS. That fix should be right
for all Amiga like OS but I don't want to change things
which I can't test.
