Fix the comments. Also a few renames like LoginController -> LoginPageController, etc.

For testing admin login: url is /admin For testing configuration generator:

• Run "./configure.py" without quotes on UNIX (after installation of mysql)
• Run "python configure.py" without quotes on Windows(after installing python and mysql and making sure both are in path). In Windows sometimes I think we get an administrator error.
