Fixed non-working anchors for definitions, made multiple complex schemas more readable

[jsorohova]

Closes: #2326, #2290

Problems:

1. Definition anchors were not working, all links were redirecting to the top of the page.
2. When multiple definitions were listed in complex schemas, they were truncated.

Solutions:

1. Fixed scrolling so it scrolls to the definition.
2. Listed every definition on the new line so they are not truncated.
