Md. Rasel Mandol

as per instruction, I have translated some messages and sent the bn.po file by replying to the previous mail.

@mirwasi , I have created a pull request from my forked repository

@mgeisler I also vote for yes.

@mgeisler I have created a PR like #730 , can you please check the PR?

> Hey guys, what is the status for this translation effort? I see it is listed as "under-progress"/"incomplete"? Would love to contribute to it. @mgeisler @raselmandol it's still under-progress, incomplete....

@mirwasi , I have signed the contributor CLA now, could you please check again?

@mgeisler, I apologize for not including the 'bn: ' prefix in my previous Pull Request. I will surely do that from next time.

@mirwasi , I apologize for the Bangla-English mixing and other translations that were not correct. I have already solved the mentioned problems but I am not creating a pull request...
