Added member model, renamed portfolio=>project in models and views
Restarted migration versions because renaming tables gives a lot of mess.

Data would have been lost anyway due to a table rename (aparently), best to start clean.
Generated index now also based on members in admin
Added unicode to member model
Fixed missing space
Removed the "' projects" suffix for person tags
Added link back from projects to members
Moved models and admin to the organisation app
Merge branch 'master' into production
