Some enhancements for VS 2010 and VS 2012 solutions

I will not apply these corrections to VS 2008 because I never used it and I do not plan to use it one day :-)

I modified .gitmodules because I made correction in the OwlPatches submodule of the OwlSim repository and commited them in my repository...and this was not a good idea, it created a mess I didn't understood.
I thought that a submodule commit will create a fork in my own repositories and will commit files in my OwlPatches fork...but no...it seems that submodules can have their own life outside their original repository.

And it seems that the OwlPatches submodule of OwlSim repository isn't synchronized with the OwlPatches repository and I don't understand why because .gitmodules references pingdynasty/OwlPatches.git.
An example : ParametricEqPatch.hpp file is different in each OwlPatches folders...well...I await your review
