Minor improvements to the run script to make it run without and give
a clearer error when nose isn't installed
Fixed erroring unit test for 2.6.
Aded tox.ini and pinned testing requirements
Corrected version pinning syntax in requirements and tox.ini files
removed itemstate check and updated since to use epoch time
[CMSVM-423] Removed __setattr__ validation
CMSVM-423 - Reverted epoch time change to assume minutes once more.
Removed failing tests that test against code we removed
Added the PENDING itemState enum, and a test for setting a video to
that state
Added validation code from __setattr__ back in as validate() and
refactored to make it check all attributes at once. Added unittests for
__setattr__ back in (with the calls to .validate() added)
Version bump to 1.3.7.cmg10
Made exceptions in validate() fail fast
