[Kst] Plugins basically done

[George Staikos]

Basic plugin functionality is done in KST now.  I am able to take data vectors 
and scalars as input to a plugin and generate output vectors which can be 
used in a curve.  However, I don't trust the stability of this yet.  In 
general it is working, but the vector/scalar and vectorlist/scalarlist 
problems are just too great right now.  There are some intentional memory 
leaks because properly cleaning the memory in some places is just far too 
complicated and hopefully reorganising those classes will make it very 
trivial.  Actually I think as much as 200+ lines of code will get eliminated 
from KstPlugin* classes alone once this is done.  I'll start working on this 
next.

Should we cut a release of the code before reorganisation?  I have tagged the 
code as it is right now with "kst_plugins_implemented" so that it can easily 
be retrieved if the reorganisation goes too far before the packaging is done.  
I can move or remove the tag as needed.
