"Use the same window" option for MuonAnalysis

[Arturs Bekasovs]

On the settings tab, add another option, which when enabled would make the interface use the same (effectively the previous) window for plotting. This should solve the problem of the new graph appearing in an unexpected place all the time.

However, sometimes it is useful to keep the previous graph as well. So the trial solution agreed on by the scientists is to copy the old graph to the new window.

Tester:

I've decided not to implement "Copy previous plot to new window before replacing it" functionality in this ticket. This is because it is quite difficult thing to do, as it turns out: lots of stuff should be fixed before I can do that. To save my self from lots of tedious work, I will ask scientists to check this version out first. Though if they will insist that they want to keep the old graphs, I will surely implement it anyhow, but in a separate ticket.

Additionally, it simplifies a life of this ticket's tester a lot. :-)

Please check the following:

1. The new option was indeed added and works as expected.
2. Switching between new plot policies on-the-go works as expected.
3. The option selection is saved between the interface runs, but defaults to "New window".
4. "Hide previous plots" option works when using "New window".

Option appears to work as expected and the code looks good.
