* [Cleanup] Gender constants cleanup
# Notes
- Convert to a `Gender` namespace using `constexpr`.
- Cleanup spots where we were using magic numbers for gender values.
* Cleanup
* [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.
* [Commands] Overhauled #npcedit.
- Added missing columns like untargetable, show_name, exp_mod, etc.
- Put stats in order of column appearance in table within help message and within code.
- Converted StringFormat to fmt::format.
- Added a GetGenderName() helper method.
- Prettified response messages of nearly every #npcedit option.
All tested and ready to go.
Would like input about possibly changing some of the command arguments to match the table column names more closely, example being "spell" should be "npc_spells_id".
* Cleanup.
* Fix indentation.
