- [X] Adds `AdhocPersistence` which replaces RunUO `Persistence`
- [X] Fixes a few minor bugs with EntityPersistence deserialization
- [X] Reverts/updates some serialization changes
- [X] Fixes generic persistence, making the API for writing from a static class much easier.
Example:
```cs
namespace Server
{
public static class ExampleSystem
{
public static void Configure()
{
GenericPersistence.Register("ExampleSystem", Serialize, Deserialize);
}
public static void Serialize(IGenericWriter writer)
{
// Do serialization here
writer.WriteEncodedInt(0); // version
}
public static void Deserialize(IGenericReader reader)
{
// Do deserialization here
var version = reader.ReadEncodedInt();
}
}
}
```
