* Adds `RaceFlag` to the `Race` object. This is `1 << RaceIndex`
* Replaces `RequiredRace` with `RequiredRaces` for items.
* Adds convenience flags for `RequiredRaces`
```cs
public const int AllowAllRaces = 0x7; // Race.Human.RaceFlag | Race.Elf.RaceFlag | Race.Gargoyle.RaceFlag
public const int AllowHumanOrElves = 0x3; // Race.Human.RaceFlag | Race.Elf.RaceFlag
public const int AllowElvesOnly = 0x2; // Race.Elf.RaceFlag
public const int AllowGargoylesOnly = 0x4; // Race.Gargoyle.RaceFlag
```
* Example usage on an item:
```cs
public override int RequiredRaces => Race.AllowHumanOrElves;
```
* Adds Wood and Stone armor material types
* Updates Woodland armor to Wood
* Adds proper messaging for race restrictions
* Adds gargoyle only for object properties
* Adds `CheckRace` functions for validating if a race or mobile can use the item:
```cs
bool CheckRace(Race race);
bool CheckRace(Mobile from, bool message = true);
```
* Adds save flag support (see `ElvenGlasses` for an example)
* Updates AOSAttributes so they are code genned
* Fixes embedded object support by adding an `IRawSerializable`
* Fixes various inconsistencies in serializing with codegen
- [X] Adds a property to `CommandProperty` to allow modifying `PropertyObject` where there is no property setter that is accessible.
- [X] Updates AosAttributes and friends
Example of how to make this work:
```cs
[CommandProperty(AccessLevel.GameMaster, canModify: true)]
public AosWeaponAttributes WeaponAttributes { get; private set; }
```
This fix is necessary because in release mode the optimizer will sometimes _entirely remove the setter_ because it knows it can do something that is more efficient _when the property setter is private_. RunUO got around this by declaring a public setter explicitly that _was empty_.

- [X] Caches DateTime.NowUtc on the game loop (not other threads)
- [X] Replaces all locations where it makes sense
- [X] Adds Min/Max for `IComparable` (TimeSpan, DateTimes, etc)
Closes#261
- [X] Fixes an issue where a buffer smaller than 8 bytes would not double with enough space in some cases.
- [X] Fixes an issue with dupe copying the savebuffer reference (ugh).
- [X] Streamlines the IGenericWriter API to use better generics.
- [X] Streamlines the IGenericReader API to use better generics.
- [X] Forces `tidying` of a List/HashSet to be done externally since Writers/Readers should not have side effects.
- [X] Fixes an issue where Tidying a list didn't TrimExcess, causing memory leaks.
- [X] Reverted the meaning of `World.Running` to specifically refer to any world state post world loading.
- NOTE: Do not use this if you want to block on world saves. Instead use checks against `WorldState.Saving` states.
- [X] Fixes an issue with serializing negative DateTime deltas.
- [X] Fixes a potential issue with serializing non-UTC DateTime.
