Extracted the servicemenu code from KonqPopupMenu into KonqMenuActions, and used it from both KonqPopupMenu and DolphinContextMenu.
 This isn't the port-to-ktrader yet, this will come later, but at least the code is factorized and the impl can be changed without affecting the dolphin+konqpopupmenu code
Should I also implement the "Open With..." actions in KonqMenuActions? Seems like another bit of similar code duplicated.

Removed KonqBookmarkManager (was a two-liner call to KBookmarkManager)
