EOS M: long-press SET/Q to open submenus
From http://www.magiclantern.fm/forum/index.php?topic=17056.msg166369#msg166369
This should make the EOS M menu navigation a little more consistent with the other cameras.
To try this on any other camera, put #define CONFIG_LONG_PRESS_SET_MENU
in internals.h. I've tested it on 5D2.
Note: I don't think it should enabled on all models, because:
- SET might not give unpress events everywhere (when it happens, ML will always think you did a long press)
- when checking for long press, the original action (short press) must be done on the unpress event, which feels a little slower than before; I've adjusted the timings to minimize the delays, but it still doesn't feel 100% right.
@nikfreak: could it be also useful for 100D, or it's better to stick with Av?
