Instead of only checking for valid request arguments by using a hmac,
we now check the complete request including action, controller and vendor
to avoid spoofing these arguments and bypassing other security checks
during forwarding to the referring action.

Additionally, ReferringRequest is now separate from regular Request.
The meaning of properties starting with "@" is only valid for
processing a referring request. To avoid mixed concerns in using
the same Request implementation for regular requests and referring
requests, they are separated now.
