Brazilian portuguese

[FKrauss]

as per the documentation I have "integrated" the pt-br language into the website and tested it locally.

Images are all in place, text is good and a few corrections were made in directly in the code so it wouldn't overflow their space.

I made a couple additions to it too:

1. I started a small tutorial on how to integrate a new language - it's not 100% great but it is a start. I'll add more to it when I integrate another language
2. included a small telegram logo in svg in the images/community folder
3. included said telegram logo in the pt-BR page for community with the link to the Brazilian telegram support group
4. removed a bunch of whitespace in the dao_content_tr.yml file

Let me know what you think!

Cheers!

@FKrauss -- some notes:

This PR was a bit hard to review as-is because of the commit history...if you look at the "Files Changed" tab on the top of this page, you'll see this PR includes a lot of changes from the extra unrelated commits. I ended up cherry-picking the commits you made to do a proper review, and would need you to do the same to clean this PR up before merging. Ideally it would also be rebased onto a more recent version of the master branch.

I did it already here on my repository. I can explain how to do it if you like, or you can give me push access to your bisq-website repository and I can just push what I have.

Some corrections:

1. These links on the bottom of the DAO page are missing spaces. I've added a suggested commit to fix this issue.

2. All pictures on the DAO page are still in English. Would you mind translating them? They're SVGs so you can manipulate the text in the SVG file. I've suggested corrections that fix this issue.

3. It looks like only some FAQ updates from the v1.2 PR made it here. For example, the payment methods section isn't current on this PR. Please check out this PR for reference on everything that was updated.

4. I think it would be better to make the language attribute in page front matter language: Português instead of language: Português (BR). The flag accomplishes the distinction between PT-PT and PT-BR.

I think this is everything, but it will be easier to be more confident once the cruft is removed and these corrections are made.

@FKrauss I've integrated all the feedback except the FAQs, which need to be updated in Portuguese (item 3 from my review comment).
