Rename obedient/fatefulEncounter to eventLegal

Per discussion on pret, `obedient`/`fatefulEncounter` has been renamed to `eventLegal`, and all related functions and constants have been modified with this in mind.

Additionally, fixed some whitespace alignment issues in `script_cmd_table.h`, `pokemon.h`, and `tv.c` from the last commit.
