Creativison changes. This change includes some cleanups, removal of mainargs.s (game console programs never have arguments), and a workaround for a problem I'm seeing. The problem is that sometimes (in fact, more often than not) the clrscr() call in testcode/lib/joy-test.c writes some garbage chars on the screen (most often a "P"). Could be my hardware (I haven't seen it on MAME), but to me the root cause is still unknown.

Fix joystick driver. Add interruptor support. Note that the joystick driver doesn't support combined movements (like left/up or right/down). This should be fixed.
