Track down and merge Raleway Dots sources

[alerque]

The sister font to this, Raleway Dots, is floating around out there somewhere. When we find the sources I would suggest doing the same thing we did for the forks of this repository: stripping it down to just sources and splicing the history into this repository so the whole family is integrated.

Impallari's site has been offline for 2+ years. Google Fonts has Raleway Dots output, but link back to the offline site. Looking at the Git history the Dots TTF file dates to the initial commit of the repo, so no hints as to sources there.

Scrounged up from archive.org, here are sources (vfb) for Raleway Dots: update-55-source.zip

It looks like there was an ever further tweaked version Pablo posted in the comments, but that zip isn't archived. There are certainly some older ones in the archive that some history could be reconstructed from.
