[baserkan]

This is a continuation of the public ticket #17708 from, now defunct, our public bug tracker ( https://www.virtualbox.org/ticket/17708 ). The intention is two fold:

1. Submitting updated translations by attaching them to this ticket.
2. Informing translators whenever updated text requires translation.
3. Reporting NLS mistakes and suggesting translation improvements.

Please read the document describing the translation process in detail ​here.
