Readable Ravelry troch Chantal B

This extension applies the Solarized Dark colour palette by Ethan Schoonover to Ravelry's new theme in order to make it accessible for those who cannot tolerate bright themes due to eye strain or other health conditions. It simply gives all pages on Ravelry this dark, low contrast colour scheme so the site is comfortably browsable for longer periods of time, whether that time be spent searching for the perfect pattern or chatting in the community forums!
