Lots of bugs solved and some new features added:

• fixed an important error that made the previous version not to properly work
• install now creates a default non-empty RSS 2.0 feed (rss20.xml), to avoid errors when subscribing if no new projects have been added since first install
• a main category is saved automatically (taking at random one of the regular categories) to avoid having a blank main category
• when assigning a new author to a project, the default order (cross_contacts_projects.order_author) is set automatically depending on the number of already existing authors. It also sets, by default, the same type of author than the existing ones
• list of projects by category can now be filtered by year and type of project
• project saves automatically when adding/editing/deleting authors, inclusions and/or relations.
  This improvement avoids data accidental data loss if project not saved before any of these actions.
