August bug fixes: Part 1

Credit to ViWalls for discovering most of these bugs in his playtest:

- Citrine City's theme has been made slightly louder.

- The book in Mr. Fuji's house had difficulties working properly, so it's been removed for now.

- Fixed issues where Silph Co. and the Fishing Rod house displayed incorrectly on the Town Map.

- Removed the unnecessary sign outside Celadon University.

- Fixed an issue where 2 NPCs in Cinnabar Lab and Pokemon Mansion, respectively, had incorrect text.

- Fixed a text issue in Pokemon Mansion where the final Mewtwo log would display incorrectly.

- Altered a piece of text in the secret area of Pokemon Mansion to avoid a text box error since the idea we had in mind for it was scrapped.

- Fixed a text issue in Viridian Pre-Gym where the text for the right-side poster overflowed past the edge of the textbox.
