Readme update, Lake of Rage changes, and must be 8-bit fixes

A slapdash of various little bits and pieces.
- Lake of Rage has a small culture entry at the top to illustrate what we're setting out to do. I mentioned the shell middens and canonised it alongside GSC.
- Move constants now have their 16-bit IDs set up
- Palfixed Feradactyl and Pupperon, fixed former's credit with confirmation from pokeoctober
- Wiped out the must be 8-bit errors on various Pokemon's `base_stats.asm` files.
- Fixed some aspects of Strong Arm and Water Sport calling garbage data; this was due to them using 8-bit comparison systems where there needed to be 16-bits. This fixes a good bit of their HM usage. Battle bugs need resolving (presumably due to a lack of gfx?)
- Fixed AI scoring with Water Sport (hopefully)
- Updated the readme with some of our progress over the past 5 months.
