Review Request: Scripting support for comic

[Matthias Fuchs]

Generally looks very nice, though here dilbert_x does not work, it won't
load a picture but will show the busy-mouse-cursor.

Additonally here it crashes if I try to load an allready cached comic.
So pressing next/prev if the next/prev strip has been watched before
leads to a crash.

Backtrace:

Application: Plasma Applet Viewer (plasmoidviewer), signal SIGABRT
