Load child theme templates before parent theme

[lukecarbis]

Closes #334.

Tested with both child theme and parent theme template files and stylesheets.

My parent template looks like this:

<h3 class="css-bugfix">parent</h3>

My child template looks like this:

<h3 class="css-bugfix">child</h3>

My parent stylesheet looks like this:

h3.css-bugfix {
	color: hotpink;
}

My child stylesheet looks like this:

h3.css-bugfix {
	color: yellow;
}

When I view the block (tested in both the editor and frontend), I see the child template / stylesheet, as expected:

In develop I (incorrectly) see the parent template / stylesheet:
