Ability to us "selector" inside "customname , and "skull_owner:" nbts

When creating a custom mob. Were not able to apply a players name or skull to the mob unless we manually code that certain players name into the nbt data.

Allowing the use of the selector tag inside of customname and skull_owner for summoned mobs would be very useful for all sorts of games.

For instance, we could create summoned mobs similar to a player that dies.. When they die. Making it apper as if they were reborn

Or.. Games where the player must fight themselves.

Or.. Games where the player must find an armor stand with there player data.

We could summon armor stands with a certain players name for instance on a pedestal to show who won 1st, 2nd or 3rd in various multiplayer games.

Summon ~ ~ ~ armor_stand {customname:selector:{@p[tag=test]}}

Currrently, were not able to add the selector option inside this data.
