Work on the Scarlet Book & Wild Data

* Wild data added to the Mt. Moon Crater
* CoolTrainer NPC (young Sada) added to the Pewter Museum of Science.
* [EXPERIMENTAL] Added the Scarlet Book to the hidden item list for the Pewter Mueseum of Science.

Notes;
* This commit will not work without SV Pokemon being implemented.
* The Scarlet Book has not been placed correctly. The tileset for the museum doesn't load properly in Polished Map, so I'm kind of stumped. Neither has Sada.

Things to do:
* Add an NPC to Mt. Moon B2F that blocks off the crater, along with a warp there. NPC should disappear when you have 8 Gym Badges.
