	   M /branches/unicode/dlib/unicode/unicode.h

	Moved some more stuff around and cleaned up the code.  The wcstombs got
	moved into the gui_core_kernel_2.cpp file since I removed it from the
	unicode.cpp file.  This was because mingw doesn't seem to support it.

	   M /branches/unicode/dlib/unicode/unicode.cpp

	mingw doesn't have a std::wcstombs so I replaced calls to it with calls to
	dlib::narrow.  Also changed dlib::narrow so it works in mingw as well since
	the previous version ended up calling something that mingw doesn't have as
	well.
