JsonFormatter not working from rake task

[svoynow]

wrong number of arguments (2 for 1) /Users/jsmith/.rvm/gems/ruby-1.9.3-p448@myapp/gems/cane-2.6.0/lib/cane/json_formatter.rb:8:in `initialize'

It looks like when output colorization was added in https://github.com/square/cane/commit/652c2f887f551a7ddf280399491312526291089a an options hash parameter was added to the call to initialize the formatter, but it wasn't added to the initializer for JsonFormatter.
