Instiki 0.10.2 Export Markup patch

If anyone is using Instiki 0.10.2 and wants the Export Markup (Textile) link to work, make the following changes to the source code:

/app/controllers/application.rb
Insert "options[:stream] = false" at line 66:

    options[:type] ||= (FILE_TYPES[File.extname(file)] || 'application/octet-stream')
    options[:stream] = false
    super(file, options)

/app/controllers/wiki_controller.rb
Insert "require 'zip/zip'" at line 4:

require 'parsedate'
require 'zip/zip'

class WikiController < ApplicationController
