Revert "Hopefully fix OnLoadCharacterSet being useless"

This reverts commit 6a68b64283b956fe37beadc86274233bb445203a.
Fixes #126
-Probably can be improved.
Remove some debug
Fixes #113
In light of recent Eureka Effect updates, and the fact that the EE is disabled by default, I feel that it's safe removing this.  FF2 really shouldn't be fixing vanilla bugs in the first place.
Remove weighdown chat spam (cc @Lawdy)
-You don't see super jump or any other abilities doing this
Actually fix #126
-Still hacky, but haven't looked at the API yet to see if there's a better way
I'm an idiot
Refs #126
Remove dev warning message
Will probably re-appear in 2.0.0 under event_player_spawn
