Draw Tool or libavogadro for periodic table palette?

So I polished off the periodic table widget in the Avogadro SVN.
There are undoubtedly bugs, but you can finally draw with any element
you want. Think of it as a “slim” version of the Kalzium window.
Carsten, did I forget any signals usually emitted from the Kalzium

Here’s the question. Should this be a part of the draw tool? Or will
we want it in the full libavogadro for access from other code?

My vote is for a full member of libavogadro. I suspect we may
eventually want to change color schemes, atomic radii, etc. Or maybe
someone wants to allow select by element using the table? It just
seems a more general functionality.
