Hardcoded low-resolution cover image URL

[bstegmaier]

Summary
The low resolution cover image is not configurable and hard-coded as /images/cover.low.jpg.

Steps to reproduce

• Remove any static/images/cover* files
• Add an image static/images/any_name_other_than_cover.jpg
• Configure it to be the cover image:

   cover = "/images/any_name_other_than_cover.jpg"

• Serve and browse the site

Result
Chrome console complains about a non-existing /images/cover/low.jpg file.

Suggested fix
How about making the low res cover configurable via e.g. .Site.Params.coverLow?
This is the relevant line:

hugo-theme-bleak/layouts/index.html

Line 13 in a8dcb79

<div class="header-cover blured-image" style="background-color: darkgreen; background-image: url(/images/cover.low.jpg)" data-src="{{ .Site.Params.cover }}"></div>

PR are welcome ^^

Sounds like a great idea. Basically making the low res version of the cover image an optional feature.
