Avoid addition of compiler's default options to the command line when the clearDefaultOptions tag is set to true.

Using MVSC compiler, nar-=maven-plugin always adds compiler options even when the clearDefaultOptions is set to true. Nar-maven-plugin add automatically (for msvc compiler) the options \c \nologo \EHsc and may add others. I've made changes to prevent such behaviour, not only for MSVC compiler but for all the other compilers too.
