Fix the overall map in item frame issue.

Maps in item frames are full of bugs.
1) It sends an update of the Maps data to ALL players in the world, not just the players tracking it.
2) It sends an update EVERY tick, not every 10 ticks as intended.

To optimize performance of maps in item frames, we will only send it once a player tracks the ItemFrame.
This means cursors will not dynamically update, but the map data should refresh every time the player moves away then back.

This should fully end the issues with them.

This commit removes the config setting recently added because it is no longer relevant.
