Redraw tray on wallpaper change, only if transparent (#2604)

The tray manager of polybar listens on multiple atoms for the background of the root window. On change of these atoms, it will redraw its window-background and message its tray-client to redraw also.

On fast changes of of background, this leads to immense messaging and eventual flickering of the systray.

This patch tries to soften the issue in a way, that tray-window and its client will only redraw, if the bar has transparency. If not, there should be no reason to redraw on wallpaper-change.

* Redraw on background change only if transparent

* Replace tab with spaces
