Nitro trial as a game mode

[Sven]

To be totally honest I don't really see the appeal of that game mode - even as a story mode challenge I don't think it's good. I think the part of having to collect things is done better in egghunt and the part of having to beat a ceratin time is better done in ghost replay race/time trial.
I think instead having egghunts on all tracks and maybe finding a good way to make it playable online would be way more interesting.
