Levels Snapped to grid + level design changes

All of the floors and walls in the game are now snappable prefabs. Also
the camera starting position is now at 0 rather than 3. I have changed
some level designs and created level 8-10.
FallingDeathScript taken out.

I have taken out the death when falling to fast. It's something that
would need explaining to the player and I don't think it's needed with
the current mechanics.
Level 1 and 6 tutorials are in.

Both tutorials have been created to help the player understand the
controls. Also textures have been added to the sides of the screen on
mobile to remind players of the controls for movement.
