[Gchemutils-main] Relase of the Gnome Chemistry Utils 0.9.1

[Jean Bréfort]

Hi,

This is a development release. As such, it is quite unreliable, and
might even not compile. Some features are known to be quite unstable and
the programs can crash at any time.

Main news are:

3d viewer:
        * Add cylinders mode.
GChemPaint:
        * use keyboard to change the nature of an atom [sr #105937].
        * use the AltGr key to change the default orientation of a
        new bond.
        * use the keyboard to change the default length of a new 
        chain to some current values (2 to 10).
        * add a new theme to support ACS standards (Takashi Suyama).
        * new API to create residues.
Gnome Crystal:
        * Initial support for CIF files (needs OpenBabel-2.2.x (svn
trunk)).
Periodic table:
        * graphs can be customized (a very unstable feature).
Library:
        * Display of 3D models rewritten, using code from libavogadro
        (thanks to B. Jacob).
        * New gcu::Residue class, for use in both calc and GChemPaint.
Other:
        * use Applications|Education|Science for help files.

A few of these features have already been backported to the 0.8 branch.
