* restructure the families index so families are indexed under both spouses, and the family name is normalised
* separate out Families section in individual and families pages so individual page links to the family page and family page links to both people
* normalise links to families so the link is only displayed if the family page is present, and the gid is included when appropriate
* remove highlighting of media subregions except in the media pages (it was confusing and not very well implemented)
* include people whose surname is absent in the individual, surname and families indexes
* html_escape names and surnames
* always display media thumbnails for first image in Gallery list (in some cases they were suppressed if they had been displayed at the top of the page)
* change partner and parent columns in families index to improve the layout of the HTML and put the comma between multiple partners in the right place
* use event description (where present) instead of just event type in back references
* fix bug in the way obj_dict and bkref_dict were initialised
svn: r20795
* internal table changed to use zero for unknown birthdates
* codecs.EncodedFile removed as I couldn't get it to work
* work around for self.database.iter under python 3 returns (binary) data rather than text
* work around for bug 6227
* various typos when latest gramps34 was merged in.
svn: r20775
* Moved routines for calculating objects to be output so they can be part of default list building classes.
* Replaced person link routine with one that takes into account whether there is a page for the person.
* Included repository reference media type and call number in the 'Repositories' section of the relevant source instead of the Repository page.
* Implemented a generalised back reference function to display the 'References' section of all pages. This recursively displays references till one is found for which a page exists.
* Removed list of people and families from heading of the event pages as these are now in the 'References' section.
* Fixed bug "0005968: Narrated Web Site not copying Source Citations files such as jpg or pdf docs to web site" and "0005946 GRAMPS failed to insert jpeg image into proper place for an event" by displaying a thumbnail for citation media in the 'Source References' section (with a link to the media page)
