Added pulverize.py, a Python version of pulverize.php

[jpwarren]

I created a Python version of pulverize.php.

Some differences from pulverize.php:

• It uses argparse to make it easy to add new commandline arguments
• -w or --workers option to specify how many processes you want to use for rendering. Default value is the same as pulverize.php.
• --dry-run option to test things without actually rendering or concatenating
• --render-only option to just do the render of tempfiles, but not the concat
• --concat-only option to concat, but skip the render stage

Doesn't show progress of the rendering subprocesses, so if you want that, best to use pulverize.php instead.

Thank you! :D

[jpwarren]

No problem. And thank you for doing the hard work of figuring out how to do it in the first place!

It's much faster rendering videos, now.

Omg, yeah. I only render about an hour and a half of video every month, and the slow rendering was driving me crazy. xD
