Title: Tags for projects and stacks

These commits add tagging functionality for projects and stacks with the help of django-taggit. It comes with a small tool for the CATMAID toolbar to view and edit tags. It also provides a new data view type: "Project tag table". With this a table can be created where each row and column is assigned a tag. In each table cell there are then the projects displayed for that particular tag combination. Also, for the existing data view types it is now possible to add filter tags. When using this, the data view will only work on projects that are tagged like specified.
