Revert "Slightly larger avatars and some box-shadow"

This reverts commit 38f5038cf0ec01dbdcaa00822cd393b285a0696e.

Random problems with, I assume, Chromium users. Ranted:
   "FUCK YOU CHROMIUM WITH VARYING FUNCTIONALITY AND CRAPPY
    INTEROPERABILITY THE NEW FUCKING INTERNET EXPLORER"

This will be back in the future with a vengeance (patches).
stopdaemons.sh: dynamic daemons list

Use getvaliddaemons.php instead of the hardcoded list of daemons
Repeat query window misplaced
UseFileAsThumbnailException (helps support GIFs)
Could not update avatar due to Bad Thumbnail parameters
No more Internet Explorer exception CSS files

IE versions older than 8 (which these were for) should no longer
be used anyway, since they are filled with security holes and not
even Microsoft recommends or supports their use anymore.
showAvatar functions deduplicated into Widget class
File basename call lacked a dot
Initial move towards microformats2

No validation has been attempted yet. Lots of changes left. This
is visibly not (very) different from the previous CSS layout. But
some simplifications have been made.

Might cause issues with local changes to themes and CSS. Also maybe
javascript which depends on certain legacy microformats elements.

The move to microformats2 is motivated by the announcement that all
microformats should be migrated to version 2, as of 2014-06-20 at:

Make sure the Attention::saveNew does not cause an exception so queue items get removed

It's less of a problem that one queue-item does not get handled, attention wise,
than that the queue keeps filling up. The typical error raised here is 'already exists'
so it's not even the case that the item won't get handled (it already has been).

The real problem is that the queue_item table accepts duplicates (content-wise) which it
should not.
