Adjust MSVC warning levels
Currently MSVC compiles a lot of code warning free that causes pages of warning spam on gcc. Therefore the MSVC warning levels need to be adjusted. The current gcc configuration is a good baseline and it should be taken care that no additional warnings are produces under MSVC that currently go unwarned on gcc.
