Set-up actions - Buddy

I am giving a shot for @Buddy's list of automation actions template.

The main reason behind having such layout and organisation is to have a flexible interface since Buddy's can (and surely will) add [more] dedicated actions to match its customer needs.

Thought to simplify the search by having the search working throughout all three categories automatically to make it simpler and reducing error rates.

Also, the experience taught me that developers hardly use a mice I thought to have a typing filter within the search bar (e.g. label:actions but also label:blockchain).

When scrolling through the page, the secondary navigation menu with the search shall be fixed to the top of the page and have its 'catalogue' title hidden, having then the entire secondary navigation small enough to have just the search.

As soon as the user types, not only the result dynamically match the search criteria, but also the categories on the left-hand side shows how many results are matching for each kind, so a number shall be displayed on the right-hand side if any matches are available.
