Update of /cvsroot/phpicalendar/phpicalendar/functions
In directory sc8-pr-cvs1:/tmp/cvs-serv505/functions

Modified Files:
	admin_functions.php init.inc.php list_icals.php 
Added Files:
	calendar_functions.php 
Log Message:
Added username/password login to access locked calendars. Moved
calendar availability logic (with support for login) to a
calendar_functions.php file.

RSS feeds support the login feature when determining which calendars
to return.

Styles updated for the login box.
