[chem]: Rename example file for cholesterol.
cholesterin.chem -> cholesterol.chem
Rename file according to current English IUPAC name convention
(with an OH as group of highest priority, it is an alcohol).
* contrib/chem/examples/cholesterin.chem: Rename this...
* contrib/chem/examples/cholesterol.chem: ...to this.
* contrib/chem/chem.am (EXTRA_DIST): Reflect rename.

[chem]: Add stereochemistry to cholesterol.
* contrib/chem/examples/cholesterol.chem: Add stereochemistry.
- The previous depiction was incomplete and did not explicitly
described the stereogenic centres as such. This information was
added with `front bond` and `back bond` as available with groff
1.23.0. If possible, future versions should use a wedge shaped
version of `back bond`.
- Particular about steroids: among chemists, it is more common to name
the four rings by A, B, C, and D. To use these labels instead of
R1, R2, etc. equally displays chem's flexibility here.
- The orientation of cycles allowed simplifying the definition of
their mutual attachment.
