Binds in submaps: New keyword catchallgreedy as automatic follow up to any prior key press

[11xx]

Hi, here's some ideas to make exiting submaps smoother.
(minor issue)

For example:

bind = SUPER, F, submap, wm-actions
submap = wm-actions

bind = SUPER, F, fullscreen, 1
# [...]

bind =      , catchall, submap, reset
bind = SUPER, catchall, submap, reset
submap = reset

Requires an extra keypress to exit the submap.

1. What about something like

   bind = SUPER, catchallgreedy, submap, reset
   

   to automatically run the dispatchers after any other prior keypress,
   like actually assigning bind = mod, key, , manually.

2. With this would it make sense to allow
   catchall or "catchallgreedy" for
   modifiers too? like

   bind = catchall, catchall, submap, reset
   

   even though bind = , catchall works for modifier key
   presses alone it does not when MOD is still pressed and a new
   otherwise expected keybind is attempted (that's why the double
   catchall lines in the example). For it catchall could
   be extended or if added "catchallgreedy" could do it
   instead of either having to be declared again on the mod field?

Thanks 😁
