Collector #1074: Change Scripts' __name__ to None, added unit tests for the effect of __name__ on class definitions and imports.

Adds an option to spawn a process and capture its I/O.  Just a
checkpoint because it doesn't do anything with the captured I/O yet.

Refactor the main SvcDoRun() method to make it a little easier to
read.  Move the details of log messages to helper methods.  Trim
comments that explain obvious code.

Make log messages read the same as zdaemon log messages.

Don't throw misleading warnings about duplicate products on product path unless there actually are duplicate products on product path.� Also, add unit tests for product initialization.

- removed redundant import

     - Range searches with KeywordIndexes did not work with record-style
       query parameters

     - Using "_usage" parameters in a ZCatalog query is deprecated and
       logged as DeprecationWarning.

ZConfig.components.logger, adding only what's special about the zLOG
version of the factory

       logged as DeprecationWarning.

ZConfig.logger.log type, since it does

the logging package; this avoids lots of code duplication

I zigged when I should have zagged in my last checkins.  The IITreeSet should remain unadulterated in the TopicIndex results, and the tests should adjust.

1) items added to a topic index PythonFilteredSet could never be removed upon a reindex, even if they no longer evaluated to be true.  This is fixed.
2) Casey informs me that a IITreeSet is better for this application that an IISet.  This should be a transparent change simply by relying on the keys method, which both have, rather than the iterable IISet.
