Normalize whitespace via lstrip Jinja parameter

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.
