Fix issue where display area does not take up full height

[kadamwhite]

See vega/vega-lite-ui#73; closes #322

This was introduced in dea6557d32c7733d220bd5dfca7bcc62f22b4dc8 while addressing an issue that prevented the bookmarks from closing: the display height issue arose due to the introduction of another layer of nesting that the CSS did not account for.

The same angular hierarchy can be achieved with less DOM nesting, so this commit addresses the overflow by removing unneeded intermediate div nodes.

Note that this did not end up being an issue with vega-lite-ui

This diff includes some indentation changes to main.html, so here is the diff with -w to ignore the whitespace:

Note that bookmarks are broken currently, but that issue occurs in master as well so the regression is not caused by this commit

What's broken about bookmarks? They work fine for me.
