Improved captions for reddit.com: includes just title and domain (but not votes)
Improved caption on sites like 500px.com, which use just numbers in alt text
Fixed & improved b5463c7c (taking save fname from caption): now
appends suffix only if doesn't already have it.  And fixed exception
when fname has no separators in positions 20..32.
Improved caption for featured thumbs on youtube.com
Bug fix: when clicking on direct link to image while popup displayed,
got exception and popup stayed up after image loaded in its page.
Fixed bugs in Firefox 15 and newer:
was getting exception TypeError: can't access dead object.

Fixed for these repro situations:
    Restart ff
    http://0.0.0.0:8000/test/TestCases.html
    captions on
    open Error Console
    Hover over http://1.0.0.0/non-existent-server.jpg for a couple seconds.
    While hovering press Command-R to reload.
    Move mouse out of hover.  Observer error messages in Error Console.
    After that every hover gives error message and popups don't appear.
    Even new tab in same window doesn't work.
    Hovers in new window do work.
    Even happens with captions off.
    Also happens if I Command-R while popup is displayed (on any site).
    Also happens if Popup takes keyboard focus is Off and do Command-L Return to reload.

Fixed one problem when moving tabs between ff windows (but other problems
remain).
Fixed google.hu and other google search sites without ".com"
to not show popup when hovering over logo or google doodle.
Merge branch 'master' into dev
Fixed so Reload doesn't dismiss popup but loading a different URL does
Changed to work with chrome:// page of gallery from PrevNextArrows add-on
New feature: [ and ] keys move to prev and next image numerically.  Works but a little buggy:

- If advance beyond existing images, you'll see the error indicator briefly, and can back-track
while it's displayed, but not after.  It might be better to stay on the last image or keep
the error indicator up (and maybe use a different error indicator in this case).

- When advancing, it sometimes redisplays the original image before the new image,
which is distracting.

- The size or aspect of the popup sometimes doesn't seem to adjust properly
for the new image.
Fixed to not try to show popup from embedded html5 video tag, e.g. on http://www.youtube.com/watch?v=zhJF_hTJ2Rw&feature=related
Fixed caption for imgur.com pages
Fixed [ and ] keys to not redisplay prev image.
Also seems to fix problem with those images having wrong
size or aspect.
Also fixed to not display image too small.

Example pages where it works on some of the links:
