Paste special

[John Tapsell]

Thomas,

  I think the "obvious" solution is to simply assume  text/*  can be
pasted as text, and other mimetypes can't.
  Maybe we can hard code in a few exceptions, but probably not needed
to be honest.

  For the usecases you specified, I don't want to think about them to
be honest.  It is totally fine for koffice programs to do something
more advanced than other apps.

  I think it would be great to just worry about "normal" programs -
kate, kwrite, konversation, konsole, etc.
