Dmd sc.ini and VS do not work well together!

Also, sc.ini global variables should be at the top most section:

> [Environment]
> DFLAGS="-I%@P%\..\..\src\phobos" 
> "-I%@P%\..\..\src\druntime\import"
> LIB="%@P%\..\lib"
These should be placed here instead of the individual sections as 
it creates redunancy and is bug prone:
VCINSTALLDIR=C:\PF\VS2015\VC\
WindowsSdkDir=C:\PF\Windows Kits\8.1\
UniversalCRTSdkDir=C:\PF\Windows\Kits\10\

or even in [Version]
