Remove unused css and reduce blockquote font-size

new_styles/new_mixins overwrote $light-grey on the desktop version with the same value $text-grey has. Because that was the only important thing new_styles/new_mixins did I removed the file and changed this variable.

Using a variable named text-gray for a border seems odd though, maybe just define $text-gray to $light-gray and $light-gray to the actual color in colors.scss?

[svbergerem]

Oh, this is actually the only place where I should have kept $light-grey because we import colors.scss at the beginning of the file. Will change this back to $light-grey. I didn't change the value of $light-grey because we also use it in the mobile version.

Prefer double-quoted strings

Should be ready to merge.
