EasyInstall now builds eggs in a temporary directory alongside the setup

script it's running.  This avoids it getting confused by projects with
non-standard distribution locations, and projects that may have various
eggs already sitting in their distribution directory.  It should probably
also do something like this for the build directory to ensure a clean,
fresh build, but it seems like overkill, since it only affects local
projects, not stuff that EasyInstall downloaded in the first place.
