Initial commit of HandBrakeCluster PHP framework

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.
