Merge pull request #145 from bhcleek/master

Fix a small grammar error and table markdown
adds permalink formatting options
Simplify permalink property

This mimics the `return 'none'` style as per @jnordberg's [comment][1] and
allows a global permalink style to be set in `config.json`.

It removes the *date* shorthand; I think its better to be explicit.

Related to #134.
