Version 4.1.0 - Database rewrite, Admin->Updates rewrite, General Cleanup

• Removed caching function
• Separated the MaNGOS Web database from the realm database
• Modified SQL install and update scripts
• Moved all configuration variables into the database (except the MWE database connection info)
• Updated module_char_rename config option to use new name.
• Deleted core\class.config.php - no longer used.
• Fixed SQL access in rss.php file.
• Added ability to sort admin->users & admin->chartools to make it easier to find entries. Still requires some work to incorporate multiple table lookups (e.g. sql joins for class/race).
• Rewrote the entire update system. No longer support updating the php files on the fly due to huge security risk.
• Created custom updater script which can be used for multiple versions.
• Changed install & update redirects to happen if directories exist. User should delete these directories when complete.
