Subject: [PATCH 1/3] Add overlay_filter param to hero headers

The `overlay_filter` param lets you darken or otherwise filter the hero header picture to make the text content pop out more.

You can use it by specifying the opacity (between 0 and 1) of a black overlay like so:

```yaml
excerpt: "This post should display a **header with an overlay image**, if the theme supports it."
header:
  overlay_image: unsplash-image-1.jpg
  overlay_filter: 0.5 # same as adding an opacity of 0.5 to a black background
  caption: "Photo credit: [**Unsplash**](https://unsplash.com)"
  cta_label: "More Info"
  cta_url: "https://unsplash.com"
```

Or if you want to do more fancy things, go full rgba:

```yaml
excerpt: "This post should display a **header with an overlay image**, if the theme supports it."
header:
  overlay_image: unsplash-image-1.jpg
  overlay_filter: rgba(255, 0, 0, 0.5)
  caption: "Photo credit: [**Unsplash**](https://unsplash.com)"
  cta_label: "More Info"
  cta_url: "https://unsplash.com"
```
