Allow Weather Ball with Rain Dance in randbats
Update Play Rough descs
Play Rough's effect chance is 10%
Rerip a bunch of move data.

I checked all the following against an X ROM dump:

- basePower (no errors)
- pp
- accuracy
- priority (no errors)
- secondary chance (no errors)
- isContact
- type (no errors)
- category (no errors)
- isSnatchable
- isSoundBased
- isPunchAttack

I also tried to check isBounceable and isNotProtectable, but they seem
to work somewhat differently from the corresponding game flags.
