Add break-word to elements holding action_url

[Nisden]

Outlook 2019 on Windows have a hard time breaking url's.
Therefor the elements that contain {action_url} will often break the layout, if the url is long.

We have added ´break-word: break-all´ to these elements to fix it, and I would suggest the same is done in the templates.

Let me know if I should open a pull request.

This was the reason why my layouts where showing broken in Outlook. One note though, the css element is called word-break instead of break-word :)
