Add script to bundle an install

Only requires python
Add installdir and bin location to install script
Explicitly add the 2.6 package deps in make bundle
Add support for Windows to the bundle installer
Fix lint warnings

Also add stderr to the bad rc exception, it generally will
have useful info.
Relax queue timeouts

This brings the idling on task queues from ~30%
to about 1-2%.  Note that this does influence the
responsiveness of the UI, particularly with interruption
and executor shutdown (from .1 to 1 second).  I think
this will be addressed when reworking the executor code.

One of the fixes for #333, but note that this is not the
main contribution of high CPU utilization so it does not
completely fix the issue, this will require changing the
multipart upload task algorithms.
Rename print queue attrs to pep8 compatible names

pep8: printQueue is print_queue
pep8: rename totalParts to total_parts
pep8: progressLength to progress_length
pep8: numParts -> num_parts
pep8: Rename totalParts to total_parts
Mark internal attributes as actually internal

Makes it easier to see what is intended to be set outside
by other objects vs. only used for internal use.
Make print queue thread safe
Remove unused import
Fix pylint warnings
Refactor call method into smaller chunks

Makes it easier to change the multipart part enqueueing code.
Extract _enqueue_multipart_upload_tasks in s3 handler
Don't require executor for BasicTask

The retries are handled as soon as the failures are detected, not
resubmitted to the executor.
Endpoint is not used in the BasicTask object
Remove unused vars
Remove cruft from BasicTask

So a lot of these args aren't used and are unnecessary.
Rewrite multipart upload algo
Fix bug for multipart detection
Fix unicode print error in integration tests

nosetests uses a cStringIO for stdout, which will
raise a UnicodeEncodeError on python2.
