[#37] Update design of confirmation letter

[cleac]

Resolves #37

Implement the updated design of confirmation letter.

@webknjaz @bluebirrrrd @anxolerd: give your suggestions of text improvements

[anxolerd]

Hey, @bluebirrrrd ! We know you're a super-dupa busy person, but could you please help us with the text of confirmation letter? We really need your help and advise ;)

[bluebirrrrd]

Hey guys,

I'll skip the part with criticism and just modify the @cleac's version below.

begin-part

Thanks for registering to the event "{{ event.title }}". Please confirm your attendance by clicking the button below.

<div style="text-align:center">
  <a href="http://reg.gdg.org.ua/some/confirmation/url" style="display: block; background-color: #1c90f3;
    width: 100px; color: #eee; border-radius: 5px; text-decoration: none; padding: 10px; font-family: arial;">I will come</a>
</div>

If you have decided not to come, just ignore this letter.

end-part

Also, adding some time limits for confirmation would be nice. I skipped this part since we don't have any features for that at the moment.

[Advice] Please read The art of business correspondence by Sasha Karepina before writing any letters of confirmation. I believe all of you will find it very helpful for further mailing (& discussions on github as well).

I decided to use mjml framework for this. After trying several of them, it looks the best and easiest as for me.

I will make detached header with GDG logo and text which have to be in every single email, like hi, pal in separate mjml file, like header.mjml for it to be easily included into every email template file and mask all html files in that folder in gitignore. Here is a conceptual implementation of concept: example. I'll make implementation in repo and push it here a bit later today

The only drawback I've found - we will have to put only absolute urls in the letter.

sounds ok

[webknjaz]

@cleac I've implemented a set of url_for() resolvers, which produce absolute URLs, they are available in jinja2 templates

@webknjaz awesome! :-)

@webknjaz is there any doc on url_for you mentioned above? I'd like to use it, but don't know where should I search it :-)
