Small fixes to the project structure.

Sorry for being on hiatus for a while. My OS X Yosemite install managed to erase my Windows partition completely, so I've been busy restoring everything!

Speaking of restoring, I cloned a clean copy of QtSharp, and thought that it could work more out-of-the-box.
Small fixes to the project structure: currently CppSharp.CppParser.dll isn't copied to the working directory. It's the only unmanaged thing in CppSharp, and Visual Studio's C# supports referencing directly only managed assemblies, so everything else is copied automatically, but CppParser isn't. It will complain about the missing file when running a clean build. Fixed that by including the dll as a reference to the project files. Also, moved the sqllite3.dll to the References folder to make it consistent. Also made a .gitignore for obj and bin, so the repo stays clean in git even after building.
