Improved database abstraction class to support insert and select queries
in various forms.
Added classes for pulling log entries back out of the database.
Updated Job class to describe a known job in the database, and added
JobStatus to track status updates on jobs.
Updated Config class to connect to the database, and load all settings
on startup.
Improved the class autoloader to support Exceptions in a single file as
a special case, and added this file.
Replaced dodgy placeholder with a set of PHP classes for displaying a
HandBrake webui.
Current code uses Smarty as a templating engine, and includes an ugly
but functional set of pages.
The HandBrake classes are at present only placeholders, and offer no
real functionality.
Working class autoloader for the HandBrakeCluster_ hierarchy.
