Edit /analysis to redirect to PB Pokedex

Mostly conducted small changes: 
- Deleted generation evaluations as PokeBattle doesn't divide analyses by generation. 
- Removed Smogon references in "a href"s and replaced with PokeBattle links. 
- Changed default command name to pbdex instead of smogdex
Otherwise, the commands and processes were left the same to reduce likelihood of errors.
