* Point to 0.1 archive of docs and site version fixes
Point to 0.1 archive of docs and site version fixes:
site.data.istio.version was used where it should be hardcoded to 0.1
(like in “our first release was …”) and vice versa (like in the footer)
There isn’t really a navigation (as I don’t know how to do that) but at
least the docs/welcome page points to 0.1
