Format list arranged by sections
Technically, they were before, but rather than having sections by
mod or gametype, I've split them into the following sections:
- Singles
- Doubles
- Other Metagames
- Past Generations

(Technically OM of the Month is its own section, to make it stand
out)

Anyway, format list sections should be fairly standardized from
now on.
Ubers is having a suspect test
Fix clause inheritance
Clauses weren't inherited into modded formats properly. This fixes
that. Also fixed: newline at the end of tier shift's scripts.js.
Implement Monotype format
Fix Sky Drop bug
It caused weird errors when the target was fainted.
Rowap Berry is now released.
Fix Rebound
It previously was using an outdated algorithm to determine whether
a move is bounceable.
