Display and edit points as unordered lists

[josephmturner]

Displaying points as unordered lists:

• Display tag label in-line to the right of the point
• Only display tag label if it is a sub-label (in other words, do not display labels such as "Actions" or "People" but do display labels such as "Connection" or "Health")
• In Point.js, set PointPreview css border to 0px
• In Point.js, change constants in contentExcerpt to

  const contentExcerpt =
    content.length > 70 ? `${content.substring(0, 50).trim()}...` : content;

• Display bullet points to the left of each point in the list

Editing points as unordered lists:

• Upon clicking a point, typing cursor appears where clicked (no box opens)
• If content is greater than contentExcerpt, then while editing point, allow the text content of the point to take up more than one line
• Pressing Return creates a new point on a new line just below the existing point

Drag events should still work on the whole PointPreview area. However, when point is being edited, text can be selected, copied, pasted, etc.
