As per the suggestions in Mantis 687 (thanks Sakai) to resolve an exception
* This won't apply to any existing inventory tables you have, but shouldn't
cause any issues with old tables either
* Made regions table name configurable (MSSQL only)
* Added a note in ini.example pointing out that the sql resources have to change if you change table names
* Removed duplicate picker method from GridData interface
[Provided by openlifegrid.com]
* 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!
