imply beer_can -> beer

BUR #5986 has been rejected.

create implication beer_can -> beer

Self explanatory, a beer can contains beer.

Depends whether we want to tag things like post #675338 as beer, when there's only leftover crumpled cans.

Crushed can is a tag. Those are usually empty.

Probably need to edit the beer wiki to something like "...used for containing beer" because as it stands it is susceptible to people asking for a -> beer alias without checking for usage patterns ("empty cans" that technically don't qualify for beer can because the current wiki definition relies on them containing beer inside).

Anyway, -1 to the implication because of all the empty crushed cans currently being tagged beer can.

For myself at least, I usually only tag beer if I can see actual beer.
