Fixed reading of dates/updated content hierarchy
Completed implementation of the database including persistence (saving models). Also minor UI changes.
Resolved merge conflicts.
Implemented functionality for the 'view' button in the ProjectOverview.
Prevented the creation date of a Project from being edited.
Added a wait cursor for save operations. Fixed the observer pattern so that it now forces all  models to retrieve their data from the database.
Allowed multiple selections when adding or removing models using the ModelChoiceView.
