Pin bookmarks buttons to the vine category buttons

[Vaskivskyi]

This PR will pin the bookmarks buttons (now, -12 h, -24 h) to the Vine category buttons instead of the search bar.

The current issue is that the buttons are pinned to the search bar (as per the wiki). Unfortunately, not all countries have the search feature at all. As a result - there was nothing to pin to (no corresponding element in the page code) and this feature of the extension was not available at all e.g. in Germany). With this small change, the feature should be available for all the users.

Very good point, but how does it rendee with mobile stylesheets?

Looks fine to me for Germany

Worth checking when a search bar is available (e.g. in the US) - I don't know how would it work there

That's not the mobile stylesheet (look in the settings, style tab).

I'm on my phone atm, driving back home. I'll check this evening.

So long as it play well with the mobile stylesheet it should be good to go, but we might want to tune up the positionning a big better (left align maybe)
