[IMP] t9n: add tab in the menu to list available projects.

This commit adds a tab in the  menu bar that lists the available
projects. Also, the form view of the project is configured to have
two tabs: one for resources and the other one for the description
of the project. Also, some security permissions have been included
in the manifest file.
