Unfortunately, the traceback.format_exc() function you used to capture
the stack trace for print out is Python 2.4+ only[1].  This means if
one of the print-and-compare tests fails with an exception on Python
2.3, then run_tests.py will fall over.  I've checked in a simple fix
to use the exception text instead - I'm sure something more useful
could be done for Python 2.3, but we'll be dropping support for this
fairly soon anyway.

This was failing for me on a "known failure", test_Clustalw_tool.py on
Windows Python 2.3, where some filenames with spaces just won't work
without the subprocess module (Python 2.4+ only).  I don't think this
can be avoided, so I've updated test_Clustalw_tool.py to skip this bit
in future.
