[BioPython] Plans for release 0.95d01

Sounds great. I just updated setup.py in CVS with a modified version
of what I posted that does smarter checking for versions, etc, based
on Jeff's suggestion.

I also updated the setup.py to install Martel once it is present in
CVS. I added a flag (INSTALL_MARTEL) in the script to determine
whether or not to install the martel packages. Right now it is off
since Martel isn't in there, but in the final release I imagine it
would be on by default. This seems to work if I just put Martel-0.5
(named Martel, of course) into my biopython directory.

What do people think? Would these work okay?
