howto: moved to wiki; see Infrastructure/Website
beerevent: updated beer menu link
beerevent: updated one more link
about: removed link to planet.fosdem.org
navigation: remove links to stale pages

A number of pages are necessarily stale until we get further along in the
organisation.  We could spend a lot of time adding conditional language,
but it's much more efficient to just remove the links for now.
schedule: remove the 'quick links' info block

No point in linking to empty PDF files and an empty schedule!
schedule: hack around absense of distro track

We haven't scheduled any tracks in Pentabarf yet.  While we're sure to have
a distributions devroom at FOSDEM 2014, we haven't decided how we're going
to schedule it yet.  Hack around the link for the time being.
schedule: remove beer event from the schedule

Arguably, the beer event isn't really part of the schedule in the
first place.
practical: remove 'during the event' links for now
content: cull stall content that may cause confusion
buildings: AW is now an office building
keysigning: typo
