* Added a hashtable based HTTP processor in preparation of the web_login_key

Browse Source 
* Added the web_login_key to the users table
* Added happy configurable http error message pages
* This update is large enough to have 'awe' value..    so backup your users or weep.
* Not tested on MSSQL, even though I added code to update the tables!
