Brunswick groundwork, misc. changes

The groundwork for Brunswick Trail events has been done. Wild data, Cactus event, and Zapdos-G events are set up, plus an NPC. This also makes the Fake Tree sprite available.

I made the warp at the tunnel in Brunswick goes directly to Celeste Hill and back. Warp tile made functional.

Many bugs right now:
- Cactus doesn't disappear after battling it. Also, making this work how I want it to is hard.
- Pokemon are encountered on every tile, which is likely because it's considered to be indoors. In trying to fix this, I seemed to completely screw up the maps, so this isn't being committed. Handle this with care.
- I made a spriteset specifically for Citrine, but it doesn't seem to be working for Brunswick, likely because Brunswick is an indoor map and thus isn't just taking it.

Misc. changes:
- Moved Sandy Shocks to a 4% encounter slot in Mt. Moon Crater to be equal to Scream Tail.
- Restored the proper translation for the "rotten PRESIDENT" scientist, courtesy of Dr. Lava and Nob Ogasawara.
