Comment sort menu: fix extra padding
Frontpage: /comments from subscribed subreddits

Previously, going to /comments on the frontpage would show the same as
visiting /r/all/comments. This switches to showing only comments from
the user's subscribed subreddits.
Comments: always set subreddit_path
Gilded icon: link to subreddit gilded listing
Wiki revisions: convert UUID to string
Userpage gildings tab: start writing

Includes backfill script to be run before the other commit that actually
adds the tab
Userpage: add /gilded/given

Shows things that the user has given gold to - currently only viewable
by the user themselves and admins.
Make public multis visible again.

Moves route for viewing what you've gilded after the multi route so it
doesn't catch multi urls.
Add tab index to listing links.

This makes it slightly easier to browse listings by keyword.
Add backend for new gold feature: "remember my visits".

Store and mark what links users have already read, even between
computers.
Add frontend for new gold feature: "remember my visits".
routing: Remove route for /doquery.

This should have gone in 5f916f5812e7c3920d0cb968470280d1198e1fff.
Remove obsolete selfserviceoatmeal.html
r.ui.Bubble: Don't position a Bubble off screen.
Show IDN on domain listings when appropriate.
Add anchor-top-left class for idn-help bubble.
POST_store_visits: Add VModhash requirement.
Feedback page update
Add "clicked" back to JSON for clients relying on it.
Hide focus outline browser styles on link titles.

Now that link titles have tabindex, several browsers outline them when
focused. Let's override that behavior so that they act the way they did
before the tabindexes.
