Pressing ESC should close windows one-by-one

[gedia]

In homer5, pressing ESC while viewing (having "in-focus") a floating window would only close that window. In homer7, all windows are closed. I do think the homer5 behaviour is more practical. Scenario:

• Perform a search
• Open a callid and navigate to the "flow" tab
• Click on an "INVITE" message from the flow, new floating window appears
• Click on a "200 OK" message from the flow, another floating window appears
• Press ESC once, "200 OK" message window closes
• Press ESC again, "INVITE" message window closes
• Press ESC again, flow diagram window closes.

If people prefer the current "clear all" behaviour, perhaps it could be configurable in settings?

@gedia wrong tree this is not in homer-app. Could you please reopen this in the main sipcapture/homer repository issues?
