Plasma goes userfriendly (III)

University consumes a lot of time these days, however there are always some minutes for continue hacking on the comic plasmoid. During the last days I cleaned up the code and added nicer buttons with icons, which appear on hovering the plasmoid. As we have support for a new comic strip (xkcd.com) now, there was the need for easy configuration. You can see in the screenshot the new configuration dialog, where you can select the comic to show. Currently the selection is hard-coded, however in future versions it shall query the supported comics from the comic engine directly.
