[Kst] dragging Kst objects

[George Staikos]

   With the new view's it's going to be quite easy to have multiple main 
windows so we will probably add them soon after they are integrated.  When we 
have this, it will be desirable to be able to drag move or drag copy plots 
between windows, and I think it will even be useful to be able to drag 
objects from the data manager.  This is fine, but we need to define the 
mimetypes for dragging.  I think it makes the most sense to allow drags 
between instances of Kst too.  Missing objects could even be transparently 
queried via DCOP very easily - that's not an issue.  The real problem is that 
we need a wire protocol for the various objects, and thus binary 
compatibility.  Is it worth bothering with this yet?   Should I encode a 
version number in the drag object instead?  Or should I just store pointers 
to objects and only allow drags within Kst instances.

   FWIW, dragging to external apps could be really cool in the sense that it 
could be used to copy plots into documents, data into other apps, etc.
