Rakefile: tweaks to get vimscriptuploader.rb working

Through experimentation, I've found that the way to get
vimscriptuploader.rb working is to:

  - pass upload credentials in via a config file found at
    ~/.vim_org.yml
  - pass the release notes in via a file pointed at by the
    --message-file option
  - pass all other options in via arguments
  - pass in an empty YAML file to keep it from barfing
