328 Channel Auto-Start capability. Adds auto-start and auto-start

ordering to each channel configuration to provide the user with greater
control over initial application startup configuration.

Adds new dialog window that displays on startup that allows the user to
invoke/cancel auto-start, or simply allow the timer to expire whereby
the channels will be auto-started.

Updates channel table model to include an auto-start column and relabels
the 'Enabled' column to read 'Playing'.

Updates channel editor to change the 'Enable/Disable' button to read
'Start/Stop'.

Changes the 'enabled' property of the channel configuration to indicate
the current 'processing' status - isProcessing().

Channel's XML configuration re-purposes the 'enabled' property to indicate
auto-start and adds a new (optional) auto-start 'order' attribute.
