updated the buildbot fileter and moved it to where a python script can import it.

buildbot_filter.py

-#!/usr/bin/env python
-import sys
-for line in sys.stdin:
-    toks = line.split()
-    if len(toks):
-        if toks[0] == "File" and toks[-1].startswith('test'):
-            print line,
-        if toks[0].startswith("ImportError"):
-            print line,
