Cleaned up the Manager setup a bit. Also fixed up interface compilance in the three current Editors.
Added the beginning of the Other Settings dialog.
Changed Employees to be a GtkTreeModel itself and to access the database directly. This should simplify things quite much... after I do the same to Items.
Changed Items to be a freestanding GtkTreeModel backed directly by the database.
Switched to an actual mock items list for Items.
Built Employees's database mock.
Added various manipulation methods to Employees.
Hoooked together Employees and Login. Passwording logins works.
Hooked together employee name and password changing.
