Some project settings cahnged and corrected

* SpatialRef3D now builds into SpatialRef3D\bin and SpatialRef3D\lib
directory
* SpatialRef3D copies (as a post-build step) the gdal, proj.4 and
Spatialref3D dll into the $(SolutionDir)$(Configuration) directory where
all the test projects are build too
* Dependency of the test projects to the SpatialRef3D project set
