Rewrite docs mentioning all the styles used

[kizu]

Right now a lot of examples in docs use only new/added styles and blocks. This is not optimal, 'cause when you'd like to just copy-and-paste a template for a block in demo, you'll need to find all the deps by yourself. This should be changed so the styl button would show all the proper styles for the block, including the deps (or we could add all-styl button or something like that)
