New WWG Logo

Hope this is the right place to file this. While generating a gopher I noticed the Women Who Go t-shirt is the old logo. There is a new one now (https://github.com/womenwhogo/womenwhogo.org/blob/master/womenwhogo.org/assets/images/wwglogo.png is the highest res I could find)

Start by inspecting the linked high-resolution asset at womenwhogo.org/assets/images/wwglogo.png, then locate where gopherize.me references its current Women Who Go logo. Done means the generated gopher uses the new logo and the existing logo-related behavior remains intact.
