Update for StS 2.0.

ZHS localization update for Rocket Booster (Rita-B)

- Added in translations for KOR (Wilde) and ZHS (Rita-B). Huge thanks to both of them, and sorry for not getting the KOR translation out sooner!
- Fix for crash with Long-Range Lance
- Fix for rare crash when cards overheat
- Probably some other minor bugfixes

It's been a while, but I actually have a bit more free time now and will try to stay on top of bug reports & UI improvements going forward.

Hotfix: Shift Guard and Shift Strike no longer gain a Cycle effect in Challenge Mode.

Challenge Mode:
Changed Challenge Mode 1: Mode cards give +1/-1 and can't be copied (ie. are Rare rarity)
Changed Challenge Mode 3: Discard 50% of your Retained cards, after gaining their Retain effects.
Added the ability to enable Challenge 1 from character select screen. Extra levels can still be found in Config.

Card Changes:
Power Up now deals 7 damage but Exhausts (until mega-upgraded).

Bugfixes:
Save State now works with Construct's other Retain synergies like Bunker.
Wedding Ring's description now remembers the cards you picked when loading the game.

Bugfixes:
- Overdrawing with the Syphon Strike power no longer causes a softlock.
- When Wedding Ring's ability tries to play an unplayable card, it no longer deletes the card; now just does nothing.

Card Changes:
Electric Armor: Only lasts for one turn and no longer Exhausts. Upgrades to reduce cost to 0.
Shift Guard and Shift Strike give +1/-1 instead of +2/-2.
Zapper is now 2(1) cost and always deals 3 damage.
Critical Hit++ no longer reduces cost.

UX:
"Unlock All" config option no longer appears if you already have all unlocks.

Bugfixes:
Fixed bug where swapping out starter relic could also grab Challenge Mode relics.
