2006 Oschersleben new AIW V0.1

My attempt at an improved AIW for Oschersleben 2006.

• Fixed jagged AI corridors
• Optimized fast line
• Adjusted pit line (entry and exit) accordingly
• Attempt (using first corner corridors) to prevent first corner pileup
• Added new parameters to AIW (e.g. slowwhenpushed=0.1)

Note: tested at 97-8% AI strength with WTCC 2006 and 2007 cars

Any feedback, suggestions, or modifications welcomed!
