Integrated basic CSV field handling into Attendee table display.
Involved converting CSVExporter into a more generic ModelTable.
Added some slightly more complex table handling so that more logic can happen.
Moved management navigation completely into event masthead.
This allows maximum horizontal space for management (especially, say, attendee tables.)
Minor text change to attendee table view.
Revert "Moved management navigation completely into event masthead."

This reverts commit 3be12bae7acf12be28b539e50dc206215d6128b3.
Changed form prefix from csv to filter--more descriptive.
This is actually even clearer.
