New menu entry for External Initiative on the web site
As discussed in the mailing list, there seems to be consensus on the following proposition:
a new top level menu entry on the right "External initiatives" (to be improved, but you get the idea), under which we can have a line per initiative (Blue Hats, OSPO++, ...) This way, so we can have a page per initiative, giving more room for news / event + easier to share (a clean URL per initiative)
