Font naming for Raleway broken during conversion

The name of the font in the ttf file changes from the original version on Google fonts to the webhelper version. The ttf from Google fonts is called 'Raleway' + weight, so e.g. 'Raleway Thin'. The version from the webfonts helper is called 'Raleway Thin Thin', so it add ''Thin to every name.

this is an issue, when using specific software that adds the font from a UI via Windows + CSS defined fonts.

Might also be an issue for other fonts.
