Updated Flickr Plugin and a number of other files

Made a few changes to the Flickr plugins to improve the display of Mailchimp email campaigns
Changed the gallery wrapper to a div with spans per image instead of using a list
Changed the 'summary' selection from 6 images to 8 images to improve how it looks on the home
page

Also numerous other changes to bring the theme inline with the existing blog network,
unfortunately I cannot remember what it is I haven't committed yet so this is a bit of a crap
commit message.
