Removed junk files which should never have been committed in the first place.
Unfortunate it is, but… We have to make separate .csproj files also, since they refer to the .vcxproj files in a way that makes it hard to use the same .csproj files from both the VS2010 and the VS2012 solutions.
Shouldn't have been version-controlled in the first place.
Added script for cleaning the working directory to make it easier to switch between VS2010 and VS2012 (sorry, Mac/Unix only for the moment. :)
Rebuilt to work with VS2012. (Oddly enough, the versions I had which I *knew* I've used with VS2012 didn't work now?!? Crazy. Oh well…)
Use separate .csproj files for VS2012 also.
