Add license information

[vazhnov]

Hello!

Thank you for your project https://omemo.top!

Could you please add information about the license of this repository — is it allowed to copy, change and use the code in any purpose?
It would be great to see any popular open source license.

@vazhnov Thanks for reminding me of this issue. Off-the-cuff I would probably just go ahead and slap a (A)GPL label onto the whole project – which would be perfectly fine by me. Buuuut - there's been lots of contributions from others which I probably would have to ask before adding a license to the whole project.

Maybe it would work if I exclude the _data folder from the license description. 🤔

That is why it is better to choose the license as soon as possible :)

Just a reminder :)
