Trainer Reset.

[Grooveski]

At the moment to clear a trainer you have to quit the game(or it might just be to main menu - I haven't really investigated that much) and delete the file manually.  Could a reset button be added to do the same job in-game?

Scenarios that require a reset:
- New session and you can't match the saved trainer - it can be frustrating and is more fun sometimes to just clear it and work your way back up again.
- Testing bike mods where the new version is slower than the old one.
