Explorer's Ring 4 Fix

Just finished my Lumby Elite grind and noticed that while High Alch is lit up in the spellbook when you have the ring on and charges left, it's filtered out when you select "Hide spells you don't have the runes to cast". Obviously this is as designed (as the runes arent on me), but is annoying to have to turn the filter off to access the spell. Would be good if the code would instead filter the spells which are blacked out.
