BasicAuthenticationAttribute now respects the IBasicAuthenticationValidator.Realm when the own Realm property is not set. IBasicAuthenticationValidator.Realm is now a read-only property (removed public set).

- BasicAuthenticationAttribute sets the HttpContext.User property when successfully validated.
- Moved BasicAuthenticationAttribute from ActionFilter to IAsyncAuthorizationFilter.
- TimeSpan.ToShortString() is now capable of negative values.

- All attributes now reside in Microsoft.AspNetCore.Mvc.Filters namespace.

  Now only HTTP Status 403 (Forbid) is returned.
- BasicAuthenticationAttribute is now in namespace AMWD.Common.AspNetCore.Attributes.
