Have setup Broadcaster and ConfigPanel classes for testing BroadcastConfigPanel.
The gtk+ tree view list design is ridiculously overkill for the simple list
that I need for displaying broadcast streams. There's an available alternative
called list box, but it's not compatible with the minimum gtk+ version 3.4.
So probably going create a custom list panel to replace the tree view provided
by gtk+.
