[PyMOL] Release v0.80 (Windows only for now)

[Warren L. D. <wa...@su...>]

Sorry about the two-month release drought -- the native OSX port has been
chewing up most of my development time lately.

I just posted a Windows build of PyMOL v0.80 along with a source tarball.  

NOTE: This release is not well tested [ that's your job! :-) ], so please
be cautious when upgrading, particularly if you are counting on PyMOL to
function on critical tasks.  I'll post binaries for other platforms
after giving this release a week or two to shake out.

v0.80 is mainly a bug-fix release, but it has few nice new features:

- "align" command attempts automated sequence and refined structure
  alignment.  Be sure to let me know what kind of mileage you get out of
  this highly experimental feature.  "help align" for info.

- optional flat-capped cylindrical helices in cartoon ribbons

- "command-name ?" will display the command's arguments -- this may help
  with undocumented commands, or jostle your memory on occasion...

- better handling of three-atom waters found in some PDB files along
  with improved connectivity for other hydrogens (fewer extra bonds).

- molecular sculpting now does a reasonable job with -CN and -C#C- 

- menu option for "white background" 

- ray-tracable 3D text accessible to developers using the CGO module
  (if you know Python, feel free to consult me on usage)

- many minor bug-fixes

Remember, new releases don't just happen spontaneously.  If PyMOL is
meeting an important need of yours, then you should protect your
interests by supporting the project with direct effort or funding  
( http://www.pymol.org/donate.html ). 

Cheers,
