Charmander & Rod House move

This adds Damien, the Charmander trainer, with text changed to be more accurate to his character.

I've also moved the Pewter Rod House nearby, as it makes more sense for it to be in the Water-type area. However, it seems to load oddly.

I have also integrated the Pikachu/Eevee Mode more, with architecture that it can make it more easily modified. This'll come into play for the Squirtle event.

I have also erased further misinformation the game gives about burns, and changed the Viridian Pre-Gym accordingly, to talk about confusion, which lacks a Trainer Tips sign.
