make a branch for 1.4 so that a 1.4.4 "emergency aspirin" release can be made for easy use in case the 1.5.0b3 release causes problems for someone.

adjusted testselectingpython.py the same way as easyinstall.txt earlier: there's no call to _get_dist() for setuptools anymore as we already have it

Adjusted the test so that it also works when you're testing with an older setuptools version and there's a new one on pypi.
In that case, the _call_easy_install call will really try to install setuptools first and execute other code paths than the test cares for.
A cleaner way does not seem possible as the easy_install code is really intertwined.

(Also stop writing doc.txt. --long-description is better. And
rearranged setup.py a little.)
