add three tabs

[geohacker]

Addresses IFRCGo/go-frontend#1009

Changes

• Adds 3 tab titles for Events
• One is by default 'Additional Information' but editable
• Snippets now take a tab number - 1, 2 or 3. This is sent in the API so the front-end can render them into different tabs.

/event/:id

name: "Test Tabs"
dtype: 66

id: 3570
slug: "test-the-slug-1"
tab_one_title: "Additional Information"
tab_two_title: "Maps and Charts"
tab_three_title: "Guidance"

/event_snippets

This structure makes sense to me

@GregoryHorvath do you mind giving this a quick review + merge?

[geohacker]

Would be great to get it up on staging as well. Thank you @GregoryHorvath!

@geohacker we'd need to check up on failing tests here :(

It seems the migrations conflict. Just run docker-compose run --rm makemigrations_merge and they should be fixed if everything goes right.

[geohacker]

Ok cool I can do that. Wasn't sure the best approach with migrations!

[geohacker]

@GregoryHorvath @batpad thank you, I just merged the migrations and tests pass. 👍
