[Victory] Initial context needed

[Ayurshi]

When the visualizer starts and no rule has been applied yet, an initial message displayed on the right panel(main screen which is currently empty) would make sense.
For instance- "Start applying matches" or "No rules applied yet"

Some default message for trivial context would also be nice. So instead of an empty windows something along the lines of „No context required“
