Shield Crouch
Allows shielding on crouch, yupyup
More specifically, impedes the usual right click interaction with the shield and replaces it with an automatic activation upon crouching
Doesn't slow you down even more when shielding, you keep your crouching walk speed
Also crouching in water whilst holding a shield will activate it
Should be able to be enabled/disabled per client (the config on the server shouldn't apply it to connecting clients)
