Design Chapters Overview Page

[gnunicorn]

We currently have the locator to show all chapters on a map. Considering how "few" active chapters we actually have, this seems like a visual overkill and we might want to make the entire thing lighter. Try to design and answer the questions:

• What should an overview chapter page look like? Maybe as a grid like on womenwhocode? Any other way?
• How to display and distinguish inactive from active chapters?

the grid layout looks good.
A Map would not look so good.
