Make Training View Configurable

The training view (aka realtime) is now configurable
allowing users to drag and drop appropriate charts
and dials onto the main view.

The controls for this view are static and comprise the
old controls with start/stop buttons, device selections etc.

I have removed deprecated code too, the following are removed
from the repository;
* ViewSelection
* RealtimeWindow
* TrainWindow
* TrainTabs

Fixes #290.
