Tag Alias: decanting -> decantering

Aliasing decanting -> decantering
(Implicating decantering -> pouring)

Reason: forum #32537 and the wiki define this as a meme tag. If we're sure no one wants to tag decanting without referencing the meme, this seems safe. If not, the perhaps aliasing decanting to pouring? I'm not sure if we should do the implication above, since the meme might be referenced without much pouring going on (see post #999704).

Practically speaking, yeah I doubt anyone will use decanting properly, but something about aliasing a normal word to a meme typo doesn't sit well with me. Decanting also isn't quite the same thing as simple pouring either.
