Since 1c3f2354f8 the keyframing settings on
Keying Sets have been incorrectly displayed as a clump of toggle buttons,
which are usually only used when only one of the options apply.
Reverting this back to how it was, while leaving bl_options in place still for
the one case where it makes sense to do it that way (i.e. for KeyingSetInfo)
