Add the separate utility class PlayButtonHelper to handle the initialization of the listeners.
The ClickListeners on playlist controls had different behaviours. This commit fixes that.
The commit also refactors the way how the app determines whether it is started for the first time. The previous version was not clean and recent in this PR caused it to fail.
The previous "main" tab is now just a normal tab returned in getTabs().
Various part of the code that used to handle channels as ListInfo now either take the first (playable, i.e. with streams) tab (e.g. the ChannelTabPlayQueue), or take all of them combined (e.g. the feed).
The following is the list of all commits squashed together:
Regain function for option `Positions in lists`

remove extra check for live streams, live streams updates just as non-live streams.
