Remove Ignore invalid Marker Icon ID's in maps
Spigot has patched this issue inside MapIcon, meaning that we no longer need to maintain this patch; Spigots patch also fixes #668 in that it will verify the length of the array, as well as protect against a negative type value being fetched from the array. Only real change is that Spigots patch returns a MapIcon.Type.PLAYER, instead of the RED_MARKER as originally PR'd by Aikar.

Subject: [PATCH] MC-111699: Ignore Improper Anvil Item Name Packets
The client is improperly sending Item Name Packets to the server BEFORE
the click event. This causes the server to reset before the click event is processed
This breaks the ability to rename more than 1 item at a time.
See: https://bugs.mojang.com/browse/MC-111699
