Game thinks some spells can be cast when they can't

Extension of related issue #6698

Note that not all of these will need to be changed - some may be intentional due to the difficulty of knowing when a card might be legal to cast; it's better to allow more freedom than less.

# Still Bugged
- [ ] Castle Garenbrig - thinks it can be used to cast non-creature spells, like Caged Sun

- [ ] Eldrazi Temple - thinks it can add {2} for any spell, not just eldrazi

- [ ] Kentaro, the Smiling Cat - Samurai think they can all be cast with Kentaro in play, even if you have no mana available

- [ ] Rosheen Meanderer - gets considered for whether spells can be cast even when they don't have X in their cost

- [ ] Sanctum Prelate - cards locked out by Sanctum Prelate still think they're castable

- [ ] Sunglasses of Urza - cards seem to think this allows for rainbow mana instead of just red mana

# Fixed

- [x] Chandra's Embercat - thinks it can be used to cast any spell, not just elementals and Chandras.

- [x] Dalakos, Crafter of Wonders - gets counted at CC for all spells, not just those it can help cast

- [x] Daze - thinks it can be cast with no islands in play and no mana sources

- [x] Firemind Vessel - two vessels think they can cast Archangel of Tithes, but because they have to make different colors of mana, they can't

- [x] Geosurge - thinks the mana can be spent on any spell, not just creatures and artifacts

- [x] Grand Architect - thinks the mana can be spent for any spell, not just artifacts

- [x] Gnarlroot Trapper - thinks the mana can be spent on any spell, not just elves

- [x] Guild Globe - two globes and four islands think they can cast Archangel of Tithes, but because they have to make different colors of mana, they can't

- [x] Jodah, Archmage Eternal - every card thinks it can be cast if Jodah is on the battlefield, even if you have no mana to pay for the ability.

- [x] Rhystic Cave - is being treated as a mana source, which it kind of isn't since you can only activate it at instant speed; it should be closer to how we handle Arbor Elf (i.e. don't count it for calculations)

- [x] Sivvi's Valor - thinks it can be cast for free, even if you don't have a plains

- [x] Willbender - thinks it can be cast at all times - including during my opponent's turn with no mana sources available. (It will only let you put it *on the stack* at sorcery speed, though it still doesn't check for any available mana sources when doing so)
