v0.78.0 Fixes 2

Hey Slappers, we've got some more minor fixes for the v0.78.0 patch from yesterday.

• Steam Rich Presence: Fixed online matches showing a score that's lagging behind by 1 goal, it will now be up-to-date when the goal is scored.
• Steam Rich Presence: Fixed custom games showing as online matches
• Fixed unlock popup cosmetic previews showing the icon as if you have it equipped
• Removed herobrine

No version change on this patch either because it's backwards compatible.

Have fun!
