Incorporate the functionality of the loadable DLL's (nhraykey.dll,
nhdefkey.dll, and nh340key.dll) into the consoletty.c code and
remove the dll building
rename sys/winnt to sys/windows
move vs (visual studio) folder out of win/win32 and into sys/windows
rename include/ntconf.h to include/windconf.h
rename winnt.c to windsys.c
place visual studio projects into individual subfolders.
This will hopefully resolve GitHub issue #484 as well.
