Added Esperanto (partial) and Pirate (by Dokument).

Cleanup of the translation files. All the *.pro files are now similar and the *.ts files are updated and ready for further translation. Newly released the *.qm files.

There's still an error when trying to change back from "ru" or "ru_RU" to any other language. However, this doesn't happen in other languages.

This is set to work with the gracefull degrade (e.g. 'de_CH' to 'de' if there is no such file).

There's no warning about the need to restart. I think it is obvious, so i don't think we need it, but i can add it if you want.
