open tempfiles, including a traceback (to determine callers) if
LOG_TEMPFILES is set in the environment when Galaxy starts. This
should be considered temporary and will be removed when it's determined
where/how this happens.
Whether running locally or via PBS, $PATH should now be handled in your
user's environment.
This also fixes problems like PYTHONPATH on the new blast nodes being
wrong (because they are x86_64 and the frontends are i686).
Note that you can actually start Galaxy without having an eggs dir now.
