Failure to pass options when a method has optional arguments

[stevenkaras]

Given a program such as this:

require 'thunder'
class Example
  include Thunder
  option :verbose, type: Boolean
  desc :foo
  def foo(arg1 = 1, options = {})
    p arg1
    p options
  end
end
Example.new.start

when executed using ruby example.rb --verbose will show an empty options hash, but when executed using ruby example.rb 1 --verbose, will show the correct options being passed in.
