BUG Display a notification after publishing a campaign

[maxime-rainville]

Use the new react toast notification to tell the user when their campaign has been published.

Parent issue

• resolves User should receive a toast confirmation when publishing a campaign #131

Depends on

• Reimplement toast in React so we can use them everywhere silverstripe-admin#1068
• FIX Update behat toast logic so it works with quotes silverstripe-framework#9770

[maxime-rainville]

Might need to wrtie some unit test and behat test + bump dependencies.

@maxime-rainville, seems to work, just need to update the text and fix travis.

[maxime-rainville]

Updated the messages and added some behat test. The behat test won't be green until the matching framework PR is merged.

Approved from UX perspective.

Code looks fine and tests fine

It might be worth creating another issue for making a toast notification for when you inline CREATE a campaign

You've got a behat timeout on travis that'll need to be fixed

Just had a glance to see if we could sneak in a "successfully added" toast notification is this PR. Sadly, it looks non-trivial.

The add to campaign logic is actually in admin for some weird reason. https://github.com/silverstripe/silverstripe-admin/blob/1/client/src/legacy/AddToCampaignForm.js

Added a follow up issue for "the add to campaign" modal #190
