When in menu/inventory, allow movement keys to cancel the inventory/skills/etc window

I've been caught off-guard so many times, by zombies/players both, when i'm in my inventory and can't hit the right buttons to close it. Sometimes i'll accidentally open my inventory when I mean to press h, then I'll press esc to try and close it, which only brings my menu, then tab, and it's a mess.

What i'm thinking: movement keys (default w/a/s/d) close current inventory/etc window. I'd say keep it the way it is for the main menu, as it could get wonky for binding keys, if you press w to bind it and it closes the menu. I think it shouldn't close the main menu though, as it'd mess with binding controls, and combat-loggers would use it all the time to avoid dying while combat-logging.

I don't see a reason why it shouldn't be thought of, but maybe someone can find a reason.
