input_common.h: Got rid of the DirectInput key code macros. DirectInput
headers are always available on Windows - it's just an opportunity for
bygs.
input_common.cpp: Added default names for keys mapped to MAME's "other
switch" type.
input_rawinput.cpp: Simulate Pause key being held for 30ms, similarly to
what's done for Caps Lock on macOS with SDL. Also added a gross hack to
give "correct" names for Pause and Num Lock.
input_sdl.cpp: Get default key names from SDL. Not really that useful
as it isn't aware of the current keyboard layout. Key map files are
still needed for anything other than a US ANSI layout.
Also added some comments.
* nintendo/nes_clone.cpp: Added Croaky Karaoke 16-in-1.
* skeleton/hudson_poems.cpp: Implemented tile flip enable flag and added Spoo Daisuki! Playmat.
* tvgames/spg2xx.cpp: Added Dora TV Globe-Trotter (France) and Lexibook Junior My 1st Drawing Studio.
* tvgames/xavix.cpp: Added Tokyo Friend Park 2.
* gcslottv.xml: Added Juu-ou Junior cartridge.
