Error support and handling for Services.Manager

[Alerinos]

There is a lack of detailed error handling, for example, during the 404 no page error there should be a backward return, we should detect where the user has been, if inside the site it returns to the previous page, if on another site it returns to the home page.
During authorization error it should redirect to login, you can make an error handler and counter which counts down to redirect to login page.

I also forgot to add returning an error in the header. Currently there is a redirect to the URL and 200. There should be a redirect and actually return an error in the header.
