Rogue Caball 3.1.1

Fixed

• WoW Forever: the PvP opener suggested Shadowstep, which doesn't exist on Forever. Shadowstep is now never suggested there.
• Stricter known-spell check for every suggestion (PvE, PvP and defensives):
  • A spell only counts as known when IsPlayerSpell / IsSpellKnown / C_SpellBook.IsSpellKnown say so.
  • A clear "no" from any of them means not known.
  • On Forever, an unanswered or hidden answer also counts as not known, so a spell name in the spellbook is no longer enough.
  • The spellbook name scan is only a fallback when no API answers, on older TBC clients.
• Premeditation, Cold Blood, Hemorrhage and Mutilate are only suggested when you have actually learned them. Otherwise the opener falls back to Cheap Shot, the builder to Sinister Strike, and the finisher to Eviscerate.
