[MTC] Mission isPossible

This is my contribution for MTC contest dec 2013.
Maze-like track with abundant use of mediatracker

Features:

- Complete mission splitted in objectives, you are the hero, ManiaPlanet the enemy
- In game messages and current objective
- Activable extras (Background Story, Briefing, Postcards of the city)
- Not just 1 maze, but 6 (Sport Center, Abstract City, Servers zone, 2 X ManiaTown and the sewers of ManiaTown)
- Each maze is different from others
- Hilarius (maybe?) anticuts and wrong ways
- Thriller ending (OMG, really? )
- Extra-detailed scenario without blockmixing (no -2 for me, thanks )

I hope you have fun!

!!! A light version of this track will released soon for slow PCs !!!
