Subject: [PATCH] Disable Scoreboards for non players by default

Entities collision is checking for scoreboards setting.
This is very heavy to do map lookups for every collision to check
this setting.

So avoid looking up scoreboards and short circuit to the "not on a team"
logic which is most likely to be true.
