Adding any_autofilter_inputs and any_autofilter_outputs static tests.
Extracting untemplated & unsafe parts of AutoPacket::Has
Implemented type independent extraction by AutoStile.

If no output arguments are provided it is assumed that all data in the slave context should be output.

This relies on collision avoidance by AutoPacket::ForwardAll. If the data in the slave context is already present in the master context (because it is the data that was previously injected) then ForwardAll will discard the data.
Added a unit test to demonstrate extraction of all data by AutoStile.
Fixed serious bug in AddRecipient. SatCounters were stored in a vector, but elements were referenced, so push_back could invalidate references.

Because SatCounters were only accessed by iteration there is essentially no loss in switching to a list, and push_back will not invalidate list references.
