WebCalendar 1.14 working with drupal 5.2

I spent some time getting this to work with the beta1 release, and it seems to be working fine now.

Issues:
1) Drupal uses session_name which is not at all PHPSESSID, instead it is an MD5 hash of the base drupal URL

2) WebCalendar 1,14 main class seems to have a bug on line 568 (unless i seriously misunderstand it). The following fixes it:
///////////// includes/classes/WebCalendar.class //////////////////////
// Use another application's authentication.
if ( ! $login = user_logged_in () ) { //Used to say: $login != user_logged_in ()
//echo "Setting to not found";
$session_not_found = true;
}
////////////////////////////////////////////////////////////////////////////
Without this modification you get a redirection loop once you get everything else to work.
Interestingly, 1.12 had it correctly.

3) Because the session_name is based on the current drupal URL, so far I can only get it to work by configuring drupal with cookie_domain set to your domain. This way drupal code uses the domain you provided and not the the current URL.

So, in drupals' sites/default/settings.php, set
$cookie_domain = 'yourdomain';
If you need to be domain-agnostic, you'll have to figure out how to fix this up better than I did.

4) Attached is the change to user-app-drupal.php
Instead of assuming that the session cookie is named PHPSESSID (which it is not for drupal, at least, not on my machine, drupal 5.2),
it sources drupal libraries to determine the name of the session cookie.
