Change icon of MainWindow, if the session icon changes
Review Request #121399 - Created Dec. 8, 2014 and submitted
Currently the MainWindow icon only updates if the window title changes, too. This is problematic, if the icon changes on other dependencies. Such dependencies would be the activity monitor or the icon change if the user toggles the "Send to all" feature. In such cases the icon of the tab changes, but the icon of the MainWindow and so the icon in the taskbar does not change.
This patch promotes the icon changes from the SessionController to the MainWindow.
Build, run Konsole. Open two tabs and activate "Sent to all" feature.
