3.0beta3 take 2 (updated release #; marked compat with 32.0a1)
Minor logging changes
Facebook.com and 500.px fixes
bug fixes: flickr, 500px, 1-pic imgur gallery, etc.

Fixed bug with flickr images from other sites
like reddit.com not being recognized.

Fixed bug in 500px.com and possibly dailymotion.com, yfrog, wired.com,
etc. not working or possibly even hanging firefox
since adding support for multi-image imgur.com
galleries.  Fixes the bug and adds limit of 5000 images
per gallery to prevent endless loop if that bug
ever returned.

Fixed bug in 1-image imgur.com galleries which would
cause the image not to appear.
