set_defaults doesn't process model_dir

[mdemare]

That means setting the model_dir in a rake task has no effect.

annotate.rb:42 has:

    [POSITION_OPTIONS, FLAG_OPTIONS, PATH_OPTIONS].flatten.each do |key|

should probably be

    [POSITION_OPTIONS, FLAG_OPTIONS, PATH_OPTIONS, OTHER_OPTIONS].flatten.each do |key|

Thanks. I'll take a look.
