replace surf_adventure_easy with surf_adventure_final

[MaKo]

Surf_adventure_easy never gets played, this version has no bonuses. The surf_adventure_final atleast has 6(7) bonuses so it would make the map more playable atleast. Pretty sure every teleport works aswell in this version if that was a problem.
Btw The whole map is the same, so u can keep the records from surf_adventure_easy and just transfer them over to the _final version.

We might do this sometime, but it's not a high priority.
