rack wants to have all headers as strings
don't set headers['status'], passenger does not like it
Fixes for HTML export
make ical and xcal export work too
Only show speakers in export, no coordinators etc
do not display HTML headers etc in export, will load it into our site
Fix so that track_events are generated again
only speakers in events view
events: make 'event info' box optional, add column for room, start time and duration
Only show public events.

This should be fixed differently, in the view or smth?
events and track_events show timing too now, so order by start_time to keep it intuitive
some fosdem specific hiding
minor changes to index page
use Schedule_view in xml to make it consistent with the other outputs
some more attempts at hiding non-public events, but the problem remains with events that are not 'confirmed': they are listed by speakers, but not returned by the View thingy
xml: no subtitle when none there and use 'tag' instead of 'slug' in the xml (as it was in earlier versions of penta)
Submission: permission fix such that submitters can edit their own profile (hackish fix!)
hide paper and language fields
event: allow the event image to be edited

For some reason, this feature was only available in the submission
interface.  Make it available in the regular interface too!
Security fix for major ruby security issue
