When opening/closing the main dialog with a single click, ignore double clicks.

A click on the tray icon closes the main window if it's visible.

Update issue #281

Add new icons for the tree view.
(Closes issue #208) : Prettier icons

Remove unused variable.

Set the explorer theme for the tree and list view controls.

Hold off showing the notifications until there is now fullscreen app active. Meaning while there's a fullscreen application running, the notifications are not shown.
As soon as the fullscreen app is closed or not in fullscreen anymore, all gathered notifications are shown.

Fixes issue #286

Force the main dialog to the front when showing it.

(Fixes issue #284) : Main window opens in the background

Swap the positions of the "Hide" and "Exit" buttons.

Follow-up to r542:
