magazine_scan to magazine_(source); removing implication to scan

BUR #6013 has been rejected.

remove implication magazine_scan -> scan
create alias magazine_scan -> magazine_(source)

I can't tag the provenance of post #4602920 without adding a wrong tag automatically.

Furthermore now most magazines also release digitally;, you can nowadays buy megami magazine issues for kindle.

On a side note I don't think the wiki of magazine_scan makes much sense.

I'm not sure what the problem is. post #4602920 isn't a scan from a magazine so of course it's not a magazine scan.

Is it that we want an umbrella tag for anything from a magazine, including cover pages, inside pages, posters, digital magazines, and printed magazines? What about fake magazine covers? In any case I'd say we should move magazine to magazine (object) and use magazine (medium) instead of magazine (source).
