buildr extension throws an obscure exception when publishing without setting publish_options

[rsutphin]

If you don't set any publish options, ivy4r's buildr extension will throw an exception like this when you invoke {project}:ivy:publish:

undefined method `*' for nil:NilClass
/Users/rsutphin/.rvm/gems/jruby-1.4.0@buildr/gems/ivy4r-0.10.5/lib/buildr/ivy_extension.rb:201:in `__publish__'
/Users/rsutphin/.rvm/gems/jruby-1.4.0@buildr/gems/ivy4r-0.10.5/lib/buildr/ivy_extension.rb:728:in `after_define'

If the default options are never sufficient, it would be nice if ivy4r would tell you that you need to set publish options rather than failing in this way.

Further experimentation shows that ivy4r would do this itself if the default publish_options hash was {} instead of nil.

should be fixed with version 0.11.0
