Implements ability for Player Heads to use CMD

[BONNe]

The player heads never used data from input item stack, and always transformed it into plain PLAYER_HEAD.

This adds new method PanelItemBuilder#icon(String, ItemStack) that applies input icon and assigns name.

When skin is assigned to player head, it will copy custom model data from template item, instead of using plain HeadCache data.

This adds ability to solve #2774 in warps addon
