startup script uses PYTHONPATH instead of sys.path

OpenERP buildout recipe

Bug Description

The openerp startup script created by the recipe sets the path through the PYTHONPATH environment variable.

This is less robust than the sys.path hacking done by other recipes : IIRC PYTHONPATH is interpreted in, and some linux distros (I've seen it on Debian Etch, don't know if it's still current) may ignore it or have the global site-packages (dist-packages for Debian) take precedence over it, which breaks the reproducibility of the buildout.

Also, creating python startups open the road to more flexibility. An example : a startup scripts for tests may want to load a cheatable datetime implementation.

update: I made the PYTHONPATH test on Debian Squeeze, and PYTHONPATH now has precedence.
That doesn't change the fact that sys.path setting is a better warranty and the above mentionned flexibility

After a bit of investigation, I conclude that the best is to use a custom interpreter to launch openerp.

 - the startup script of openerp 6.1 is not modular enough yet (the if __name__ part does not relay to a single callable). Therefore, simply doing as for console_scripts would not work right away (or would lead us to unwanted code duplication) ;
- we want to support from 6.0 up anyway, and the custom interpreter can bring the kind of uniformity we need.

This can be done by giving the 'interpreter' option a default value.

For OpenERP >= 6.1, the work done in this branch is now deprecated by the better solution done for #1019886

Now obsolete in all supported cases, unlinked the experimental branch
