- Significant A_RadiusGive update.

Browse source 
- Added filter and species parameter.
- Added new flags: RGF_INCLUSIVE, RGF_ITEMS, RGF_KILLED, RGF_EXFILTER, RGF_EXSPECIES, and RGF_EITHER.
- RGF_ITEMS: Items can receive inventory.
- RGF_KILLED: Actors who are truly dead might not be corpses, and vice versa.
- RGF_EXFILTER: Blacklists the specified actor filter. All but the filtered actor can receive the item.
- RGF_EXSPECIES: Blacklists the specified species. All but the filtered species can receive the item.
- RGF_EITHER: The actor can receive the item if it satisfies either the filter or the species. Only useful when both are used.
- RGF_INCLUSIVE: An actor marked as more than one pointer to the calling actor can ignore the exclusion pointers, but only if at least one is missing. I.e. an actor who is a target and tracer of the calling actor can still receive the item, if the calling actor doesn't pass RGF_NOTARGET and NOTRACER at the same time. RGF_INCLUSIVE only works with the pointer filtering flags. By default, if not specified, the actor will not be loopholed the item if they are under any one of the three filters.
- Fixed discrepancies and dependencies upon several flags and actor conditions which caused the function to fail.
