Prerequisite: you'll need OpenBabel SVN revision at least 1525.

Reorganization everywhere, especially:
 - Make much more use of OpenBabel, especially for the geometry-stuff
 - Molecule rendering style and related data is now stored using the
MolStyle struct.
 - Big reorganization in the way display lists are used, when this
option is enabled. It is currently disabled, though, because of what
might be a bug in Mesa3d.

New Features:
 - draw multiple bonds
 - support for van der Waals radius. Different atoms are now rendered
with different sizes.

Optimizations:
 - the sphere now uses 2x less memory when not using display
lists (achieved by using the same unique array as vertex&normal arrays)

Other changes:
 - improved specular color computation in Color::applyAsMaterials()
 - reorganized styles, removed "lines" style (looked useless, was
inconsistent with multiple bonds)
 - when the uses clicks "cancel" in the Load molecule dialog, don't try
to load the molecule with filename "".
 - lots more that I can't list
