Attraction Support

[Jetz72]

First draft of Attractions. Still has a few hurdles to clear but you can add an Attraction section to a deck and play them in game (with deck conformance disabled since there are only two so far).

The weirdest new component to all this, and one I was most looking for feedback on, is something I'm calling "functional variants" - a property used to reconcile different prints with the same card name having different behavior (namely, the lights).
The script for an Attraction looks like this:

Name:Information Booth
ManaCost:no cost
Types:Artifact Attraction
Variant:A:Lights:2 6
Variant:B:Lights:3 6
Variant:C:Lights:4 6
Variant:D:Lights:5 6
K:Visit:TrigDraw
SVar:TrigDraw:DB$ Draw | SpellDescription$ Draw a card.
Oracle:Visit — Draw a card.

The lines beginning with Variant:Name match to the same name specified in an optional additional parameter in the edition file:

218a U Information Booth @Gaboleps $A
218b U Information Booth @Gaboleps $B
218c U Information Booth @Gaboleps $C
218d U Information Booth @Gaboleps $D

When a card is generated via CardFactory, if there's a variant name specified for the paper card, any matching Variant lines in the script will be applied in addition to the rest of the script. So far it's only been tested with Lights, but it's designed to work with any property. The intent was that it would also enable implementations for some variants of other Un-cards, such as Everythingamajig and Garbage Elemental. There are still some parts of the implementation that need smoothing out, but it works as a proof-of-concept for now, and some input would be nice before spending more time polishing it up.

I think most of the rest is relatively straightforward, with the Attraction deck largely precedented by Planechase and Scheme decks. There are still some things left to do, which is why I'm putting this up as a draft for now. My list includes:

• Prize keyword
• TriggerClaimPrize
• Mobile Deck builder support
• Adventure deck builder support?
• Figure out the merge move logic - If you animate one, mutate something onto it, and then it leaves the battlefield, where does it end up? Does it matter if a token or commander is involved?
• "number of attractions you visited this turn"
• Deck generation rules - attraction synergy + generating an attraction deck if needed
• AI logic
• Detail description for Visit keyword. Currently shows Visit:TrigScry
• Attraction roll result dialog has an extra "Result:" in its text

Nice-to-haves:

• Astrotorium card backs
• Light icons in the card details instead of numbers
• Reorganize RollDiceEffect.rollDiceForPlayer to remove dependency on SpellAbility - Right now rollToVisitYourAttractions() copypastes most of rollDiceForPlayer
• Move functional variant properties to a different ICardFace implementation (Tried it; turned into an exercise in code duplication without much obvious benefit. May revisit someday.)
