Modular settings in v4

[JacopoWolf]

So I was planning for v4 development and tough that the settings object is kind of a mess to work with.
A couldron with random methods you have to know of to use. Although i made my best to made the methods extremely easy to use, I still think there is room for improvement.

My idea is to modularize the settings object, having multiple nested objects rapresetings a subset of options.
For example, a StackWrapperSettings.Mask to serve as a whitelist and blacklist manager, a StackWrapperSettings.Injection to hold injeciton-related settings and so on.

I believe the initialization only using static methods is in line with the design of the library, and i would like to expand on that.

The final design would look something like this:

var settings = StackWrapperSettings.With(
      StackWrapperSettings.Mask
         .WhiteList()
         .Register( typeof(SpecifcClass), typeof(OtherSpecificClass) ),
      StackWrapperSettings.InjectionOptions
         .VersioningMethod( ServedVersionTargetingMethod.LatestMinor )
         .LimitInstancesCount( 4 )
         .RemoveUnusedTypesAfterInjection(),
      StackWrapperSettings.RuntimeOptions
         .WhenNoMoreTasks( AsyncWaitingMethod.Exit )
)

This could also allow the injection of a custom class to validate injected classes before or after initialization.

Waiting for your feedback!
