Add a timer "only when inputting" option

[mmvanheusden]

Describe the pull
I added a timer option that when enabled, timer only works when the player is inputting.

Describe how this pull is helpful
This is helpful for flagging less.

Additional context
I am a bit rusty, so the if statement can probably be simplified.

when you are standing still, even with timer enabled, you arent sending many movement packets

Not when the player is riding an entity
