x-teaser-timeline: Add IE-specific CSS grid syntax

Add some IE specific CSS grid syntax

The layout was broken in IE11. Strangely though, autoprefixer should‘ve taken care of most of it as it does in the [next-article app](https://github.com/Financial-Times/next-article/blob/master/client/components/grid/_helpers.scss)

This fixes the more immediate issue however.

x-topic-search: v0.0.3

• Pass csrfToken for x-follow-button
• Add topicFollowed/topicUnfollowed externally triggered actions
• Change from followedTopics to followedTopicIds
• Remove onBlur which hides result
• Pass followedTopicIds into SuggestionList to update FollowButton
• Disable input box's autocomplete
• Update x-follow-button to 0.0.11

x-follow-button: Remove CSS comments

...as they cause issues when other components import these styles using CSS modules :global

Remove from myFT => Added

Better handling of empty teaser group

E.g. don't show empty "Earlier Today" group when latestItemsTime time is set and all today's articles are "latest".
