Deletes uncompleted tasks

Readds JSF code and fixes several things
- Persistence unit definition files were repeated accross modules. This
 is not ideal because it opens the possibility of them becoming out of
 sync, and using symlinks is awkward in Windows. More importantly,
 though, this also caused definitions to be overwritten in the result
 WARs and JPA failing to locate the domain entity classes. An
 alternative way to fix this would be adding <class> elements to the
 unit definition files, but that just adds even more complexity. Let's
 see if Java EE is concise and DRY for once...
- JSF code that did not work was added.
- Code added in previous commits, namely test, JSF controller and EJB
 code was refactored and simplified.
