Subject: FR 2810959: If a player reads a spellbook which is in inventory, then
 looks at     a spell's description, pressing 'M' will try to memorise that
 spell from     that particular book.

FR 2815575: Instead of moving "spell levels left" to the top of the spell
    memorisation menu, make it light-green in color.
