[svn] Add photos wiki syntaxes: e.g.

[[display:centre photo:andyc.jpg]] where centre is a class applied to image, and andyc.jpg is the filename of a Photo model instance. Image will be displayed as thumbnail with link to full size image.
[[photo:andyc.jpg]] will produce a link to the admin page for the andyc.jpg Photo model instance.
[[photo:andyc.jpg Title of the link]] will produce a link to the admin page for the andyc.jpg Photo model instance with link text "Title of the link"

 If you want to work on the source code and be able to commit, you will need to use https instead of http, and your google account will need to be added to the troggle project members list. Contact aaron dot curtis at cantab dot net to get this set up.
 
 Next, you need to fill in your local settings. Copy either localsettingsubuntu.py or localsettingsserver.py to a new file called localsettings.py. Follow the instructions contained in the file to fill out your settings.
