QuickShow: Miscellaneous improvements

Browse source 
Major changes are:

The layout and mouse handling has been rewritten to always center
images in the window.

QuickShow now accepts multiple images on drag and drop. The first
image gets opened in the current window, further images are opened in
new processes.

QSWidget now loads images on its own with QSWidget::load_from_file().

An on_drop callback has been introduced for QSWidget.

Added an open menu.

Added an about box and placeholder icons to the application.

QuickShow now starts without loading the sunset-retro wallpaper.
