Bump version to 0.0.4.
Add 'ignore' action which does nothing (useful for overriding defaults)
Use selector-first syntax in HTML transforms to match cheerio API
Allow much cleaner multi-line syntax for transforms that add several lines (see README)
Add a hacky work around cheerio not being able to output non-HTML by replacing {{&gt; with {{> after a transform action. This allows for partials.
