Improve GUI responsivness

After pressing the active-only/all switch button, refresh the list immediately, rather than wait until the next refresh period (3 sec or so). This makes the impression that the manager is very slow, or the system is heavily loaded.

Similarly, after the user brings the manager window in via the tray icon, draw the list immediately, and avoid showing the empty grey windows for a while...

And, while at it, change the semantics of how the tray icon works -- currently it always toggles the display of the manager window. So, if a user switches to another desktop space, and see no manager window (or covers the window by other apps), but the window is open, then clicking on the tray icon will actually... hide the window, and the user needs to click it again. This is counter intuitive. Instead, we should ensure that clicking on the tray icon always opens the manager window and brings it as active window. To close the window, the user will just click on the [X] icon in the window decoration, as for any other app.

Switching between show_all and show_active_only works significantly faster now.

The empty grey window is still shown for a while ( although shorter), but I'm afraid that's a normal behavior while painting QTableWidget.

As of 1.2.20, this all seems to be working fine now. Closing.
