Remove Hugo Smorg Theme

[onedrawingperday]

The Hugo Smorg Theme does not have its demo generated.

There is an open issue since the 3rd of September about a mediaTypes ERROR. This same ERROR breaks the demo on the Themes website.

This theme had its last update on Apr 27, 2018.

Related: #430

EDIT
The ERROR that breaks the demo from the Netlify deploy log:

10:09:09 PM:  ==== PROCESSING  hugo-smorg  ======
10:09:09 PM: Building site for theme hugo-smorg using its own exampleSite to ../themeSite/static/theme/hugo-smorg/
10:09:09 PM: Error: MediaType.Suffix is removed. Before Hugo 0.44 this was used both to set a custom file suffix and as way
10:09:09 PM: to augment the mediatype definition (what you see after the "+", e.g. "image/svg+xml").
10:09:09 PM: This had its limitations. For one, it was only possible with one file extension per MIME type.
10:09:09 PM: Now you can specify multiple file suffixes using "suffixes", but you need to specify the full MIME type
10:09:09 PM: identifier:
10:09:09 PM: [mediaTypes]
10:09:09 PM: [mediaTypes."image/svg+xml"]
10:09:09 PM: suffixes = ["svg", "abc" ]
10:09:09 PM: In most cases, it will be enough to just change:
10:09:09 PM: [mediaTypes]
10:09:09 PM: [mediaTypes."my/custom-mediatype"]
10:09:09 PM: suffix = "txt"
10:09:09 PM: To:
10:09:09 PM: [mediaTypes]
10:09:09 PM: [mediaTypes."my/custom-mediatype"]
10:09:09 PM: suffixes = ["txt"]
10:09:09 PM: Note that you can still get the Media Type's suffix from a template: {{ $mediaType.Suffix }}. But this will now map to the MIME type filename.
