Adding New employee

[ugintl]

When I try to add a new employee, I see 2 problems:

1. There is a "username" field in the "Add New Employee" page, whereas the database table of employees does not have a "username" field. Also the username is not shown on the profile page.

2. New employee is created, but I see following error

You can see the username field in the above screenshot
