[#780] My projects page in MyRSR

Added (paginated) data to the my projects page, showing all projects (published and unpublished) of the organisations the user is connected to.

In addition, there are three 'action' links:
- View (always shown), points to project page
- Edit (only for superusers, etc), points to project admin
- (Un)publish (only for superusers, etc), points to publishingstatus admin
