Make our theme loading a little more Rails 1.1ish. Should now work with respond_to
user
```ruby
module ThemeHelper

  # NB: This overrides an undocumented rails function in order to add
  # a search path. We need this to get themes working, but I'd be
  # happier if we didn't have to override undocumented methods. Ho
  # hum. -- pdcawley

  def search_paths
    ["../themes/#{this_blog.theme}/views",     # for components
     "../../themes/#{this_blog.theme}/views",  # for normal views
     "."]
  end

  def full_template_path(template_path, extension)
    search_paths.each do |path|
      themed_path = File.join(@base_path, path, "#{template_path}.#{extension}")
      return themed_path if File.exist?(themed_path)
    end
    # Can't find a themed version, so fall back to the default behaviour
    super
  end
end
