fix($CNAME): Move CNAME

I believe having it in the root of the 'master' branch is what is causing
GitHub to resolve the URL for this site to a 404. I'm moving the CNAME
to the src/assets/ folder and using a build task to copy it over.
fix($templates/partials/git_info): view source url

closes #1
fix($templates/partials/credits): static txt files

were not being rendered with the correct URL, or -- in the case of hackers.txt
-- not rendered at all due to a bad path to the node binary.
fix($templates/{index,layour/post): Datetimes

Fixes the dateime output in `<time>` tags. Also allows for formatting of dates
based on the first and last commit.

Added dependency: moment.js

Breaking changes:
- must pass an extra parameter (empty string or moment.js date format string)
as second parameter to the `add_date` and `edit_date` template helpers.

fixes #2
