Just another minor patch, fixing problems in some levels.

• You no longer go out of water state when swimming through the pipe in mission 7.
• One of the targets was randomly disappearing in mission 7, making it impossible to complete. This is now fixed.
• Fixed an easy way to get out of bounds in mission 7.
• Mission 6 is now slightly harder to speedrun.
• Mission 6 target has new dialogue.
• Minor increase in fall damage to make some tricks a bit harder.
