Authentication functions.

This file contains all the functions for getting information about users. So, if you want to use an authentication scheme other than the webcal_user table, you can just create a new version of each function found below.

Note: this application assumes that usernames (logins) are unique.

Note #2: If you are using HTTP-based authentication, then you still need these functions and you will still need to add users to webcal_user.
