Visual C++ Projects: Split the Property Sheets

Visual C++ Projects: Split the Property Sheets

This will make the single property sheets split into multiple property
sheets as:
-They will be easier to maintain
-Individual Projects can include them as needed
-Easier to automate the listing of headers to "install"

Also update some parts to improve the overall build experience,
specifically combining macro defs and using a custom build rule for
config.h.
