Site updated again

[Ate Douma <at...@douma.nu>]

I just updated a fully re-generated portals site as it was missing out many changes like description of the bridges 
subproject, navigation links for both bridges and graffito etc.
I also added a release note about Bridges 1.0

What I do see happening is some of us updating only a single page which they generate locally first.
That works *only* if you happen to have an up-to-date local definition of the whole site. Otherwise you end up
overwriting (navigational) changes made by others.

And seemingly some changes were never committed in the first place.
By uploading a completely re-generated site from source I now might have overwritten some changes (although I
don't think so, I added a few changes first myself).

Please, lets all try to keep the portals site *and* its source tree in svn up-to-date!
