Translate extra and Nethforge modules

[jgjimenezs (Jose G Jimenez S)]

@alefattorini @davidep Friends, you can place the module Transifex dynamic DNS service for the translation?

[davidep (Davide Principi)]

Sure, I’ll send a pull request to @stephdl!

Here is the new resource on Transifex, the pull request on GitHub and the I18n guidelines for developers.

For now none of my modules have translations but I do love the idea to get them.

Thanks @davidep
