[Bug Fix] Fix Appearance Issues (#3520)

* [Bug Fix] Fix Appearance Issues

# Notes
- Changing race, gender, or texture of a Mob could result in it changing sizes due to use not sending the size as part of the appearance packet.
- Also converts the parameterized method to a struct parameter so that we can optionally send things without back-filling multiple arguments.

* Gender cleanup.

* Fix.

* Formatting.
