This adds the lstrip_blocks Jinja parameter and removes unnecessary
whitespace from a few notmyidea templates.
Note: The lstrip_blocks parameter requires Jinja 2.7+, which has been
noted in Pelican's setup.py.
Credit for this commit goes entirely to Russ Webber, who has earned my
eternal thanks for discovering and applying this useful Jinja parameter.

I'd added them earlier to test that a configuration edit could
preserve the original output locations. However, it is likely that
you have quite a number of static files, and we shouldn't recommend
listing explicit paths for all of them. With this configuration
change, the pictures will be copied into the output directory using
their original relative path (e.g. `pictures/Fat_Cat.jpg` without the
`static`). Any |filename|-style links will be updated automatically.
If you *want* the pictures to end up in a `static` directory, it's
easier to just organize your source that way.
