Eldritch Moon rules and Oracle update

# Rules

The following rules changes from EMN may be relevant for XMage:
- [ ] Two new rules related to timing:

> **601.3a.** If an effect allows a player to cast a spell as though it had flash only if an alternative or additional cost is paid, that player may begin to cast that spell as though it had flash.
>
> **601.3b.** If an effect allows a player to cast a spell with certain characteristics as though it had flash, that player may consider any choices to be made during that spell's proposal that may cause it to have those characteristics. If any such choices could cause it to match these characteristics, that player may begin to cast that spell.
>
> _Example: An effect says that you may cast Aura spells as though they had flash, and you have a creature card with bestow in your hand. Because choosing the bestow ability's alternative cost causes that spell to become an Aura spell, you may legally begin to cast that spell as though it had flash._
- [ ] A mana ability can no longer be used to pay for itself:

> **605.3c.** Once a player begins to activate a mana ability, that ability can't be activated again until it has resolved.
- [ ] Permanents entering the battlefield at the same time as [Sutured Ghoul](http://mtg.wtf/card/m12/112) can no longer be exiled to its replacement effect:

> **614.13a.** While applying an effect that modifies how a permanent enters the battlefield, you may have to choose a number of objects that will also change zones. You can't choose the object that will become that permanent or any other object entering the battlefield at the same time as that object.
>
> _Example: Sutured Ghoul says, in part, "As Sutured Ghoul enters the battlefield, exile any number of creature cards from your graveyard." If Sutured Ghoul and Runeclaw Bear enter the battlefield from your graveyard at the same time, you can't choose to exile either of them when applying Sutured Ghoul's replacement effect._
- [x] New keyword action: meld
- [ ] Offering has been reworded, this is related to the new 601.3a and 601.3b
- [x] New keyword ability: emerge
- [x] New keyword ability: escalate
- [x] You can no longer look at the sideboard of a player you control (as far as I can tell, this was never implemented in the first place)
- [ ] Turns of players who have left the game are skipped:

> **800.4i.** If a player who has left the game would begin a turn, that turn doesn't begin.

Start with the unchecked rules entries, especially 601.3a/601.3b, 605.3c, 614.13a, offering, and 800.4i, then verify which card checklist items remain. Trace the existing Java rules and card entry points for those mechanics; done means the remaining Eldritch Moon rules and cards are implemented and the issue checklist is complete.
