Metapackage to setup and configure a "Master Backend" profile of MythTV

 This Meta-package will install and configure all necessary packages for this
 machine to behave as a "Master" Backend for a mythtv network. This package
 is intended to be installed on the machine that will behave as the first
 (and possibly only) backend for the network. Typically, this package will be
 installed on a server rather then a desktop. It makes no sense to install it
 on anything but the first backend machine on the network.
