Provide a rake task or command line exe option that will auto convert *.bproto to Ruby

[davebenvenuti]

For example, if I have a directory listing like:

- myproject/
  -  foo/
    - something.bproto
    - somethingelse.bproto
  - bar.bproto

it would be cool to run something like rake protoboeuf:generate or protoboeuf generate and end up with:

- myproject/
  -  foo/
    - something.bproto
    - something.rb
    - somethingelse.bproto
    - somethingelse.rb
  - bar.bproto
  - bar.rb
