Add Romanian localization

[BootVirtual]

I finished almost all strings except for the ones containing the word "pledge". I don't really understand what it means in these cases. Ping me if you need anything!

Edit: I forgot to add, this pull request is for Hacktoberfest

Pledge means that you intend to purchase the item and give it to the person. It means that other people won't give the same gift because they know you are giving that gift already. Does that make sense? @BootVirtual

Alright, I'll add another commit later today or sometime this week.

I finally managed to get the whole thing translated. Thanks for your help!
