Use the DecompilerSettings.Other resource key consistently

Four settings used the bare category string "Other" while the rest of
the group uses the "DecompilerSettings.Other" resource key. Both happen
to resolve to the same English text today, so the options UI shows one
group, but the two keys would split into separate groups the moment
their translations diverge.
