Compare single-paragraph text block to multi paragraph text block

[jasmussen]

We are exploring two approaches for wrangling text in the editor:

1. a paragraph is a single block with controls docked at the top the block (mockup, ticket)
2. multiple paragraphs in succession is a single block, with controls docked at the top of the block (mockup, ticket)

We should build both, see which one works best, and keep only the one that works best.

In the continuous text mockup, quotes and lists are part of the toolbar. Selecting one of those options after having selected one or multiple paragraphs could either split the block when the selection is converted.

Both blocks are in master, and they work well together. If you just write, you are in a continuous text paragraph block. If you double-enter, you split it, if you backspace, you merge back again. Let's keep this as is for now, until we start really dogfooding this thing. Closing as fixed 🎉
