imgur.com fix for imgur.com/gallery/ links.

It used to assume the link was to a single-image gallery, and
directly display the corresponding jpg.  But occasionally the link is
to a gallery of an album, and the generated link is to an unrelated image.

To avoid that problem, we display /gallery/ links using
OthersIndirect, which gets the right result in both cases,
but is slower.
Revert "imgur.com fix for imgur.com/gallery/ links."

The fix solved the particular problem (http://www.reddit.com/r/pics/comments/1vaoc1/does_reddit_like_fish_tanks/) but it slows pop-ups for thumbs on
imgur.com itself since they have to come from others-indirect.
Since the problem seems to be uncommon and since merging the
change into imgurAlbums thread didn't work right, I'm
backing the change out.

This reverts commit 46ce43be55d79f2a228a31c26f3f292a2284ede9.
