[ODE] Most tests now take the path to the texture files as arguments

[Rodrigo Hernandez]

... or default to the string already in the code if not provided, there 
were 2 tests test_collisions and test_joints which already take 
different arguments, I opted to just not update those.

Also I added a project to build drawstuff on VC++7.1 for building tests.

Cheers!
