Some items are still missing / not functional like updating the program

More work on the two pane layout for the channel list.
Preselection of the first item is still missing.
Replace the fragments instead of adding them. Also use some fading
animations.

Save the selected channel position.
More work on the dual page stuff. Automatically select the first channel
when loading is done.
Only preselect the first channel in dual pane mode.
