Use move action keymap for directional input

I use customized vi-keys with 'y' and 'z' swapped for use on a QWERTZ keyboard. I swapped the keys in keymap.txt and keybindings.json, but noticed that it had no effect on stuff like "Examine" etc.

I came up with this little hack - I realize that this code is probably due to be properly reimplemented using input manager - but in the meantime, this "works for me" (tm).
