OBDepict: Draw aromatic rings first to ensure all double bonds are
inside an aromatic ring.
Darken Pt color for depiction, as suggested by PR#924.

Patch from Torsten Sachse to re-enable minimizing rmsd and minenergy.

Conformer searches that perform a geometry optimization before
calculating the energy or RMSD to eliminate minor clashes.
Make sure all SDF templates are installed for use with 2D layout.

Also add a DABCO template.
Fix --fillUC wrapping with duplicated atoms.

Different atoms could be transformed to the same symmetry spot.
The simplest solution seemed to be to check that there isn't an
existing Cartesian atom after ensuring there isn't a duplicate
fractional coordinate. Credit to Michael Moody for the bug report.
Better ensure forcefield convergence by checking maximum gradient.

Maximum gradient for convergenece is 0.1. No interface for changing (yet).
Also switch conformer searches to use Conjugate Gradients.
(Tests indicate that greater minimization is achieved in most cases using CG)
Fix bond typing for conjugated sulufurs in rings.

Only allow single bonds to ring sulfurs, e.g., methylene-dithioles.
Aromaticity detection will attempt to aromatize, but unset these
and reset as single bonds.

Change cout to obErrorLog in cifformat

Instead of a specific `v` option for the CIF format to show verbose debug messages, instead use the global `---errorlevel 4` option.
