Fix #637: nose install fails w/ traceback using python 3.3.0

To cope with multiprocessing, nose attempts to rewrite some scripts.  It
turns out that some of the "scripts" are actually executables.  Under
Python 2.x, we'd just perform the substitution on the executable too,
but it never matched anything, and therefore, never replaced any bytes.
Under Python 3, that tactic no longer works because the scripts come as
a string, while the executables come as bytes.  We shouldn't try to
rewrite an executable anyways, so let's just skip them.

Fix a twisted test to work with Twisted 12.3.0 or better.

Twisted has updated trial to work better with unittest's test runner.
As a result, skipped tests are no longer reported as failures.  Since
this is the desired result, fix the test to no longer expect a failure
for the skipped test.  This was tested from Twisted 10.0 to 12.3.
Fix broken duplicate handler detection.

The old logic is broken (at least with newer versions of Python).  New
handler objects are created, and there is no mechanism for comparison,
so it resorts to using the object id.  This means that duplicate
handlers are not detected at all.  Let's check the baseFilename of
FileHandlers and the stream attribute of StreamHandlers as a way of
detecting duplicates instead.

With this change, the repeated log messages are greatly reduced.
