language.hpp: fixed, need to use GetUserDefaultUILanguage rather than GetUserDefaultLangID.
Prepared emulation.cpp, will contain the plumbing that holds everything together.
mhookpp: added missing Windows.h (required because mhook.h happily uses symbols from Windows.h without including them itself)
mhookpp.hpp: was missing outer namespace ftw7_core.
emulation.cpp: sketched out some initialization code.
