Fix the popup versions of qt_yn_function() to handle control characters by using the same key press event decoding routine and menus and extended commands. Moves 'keyValue()' to qt_key.cpp and its declaration to qt_key.h, requring several files to start using #include "qt_key.h". 'make depend' update to follow.
