Adds support for dynamically setting the title

Adds support for dynamically setting the title

Adds a colored title area. When the title is set, it will be exposed
with a simple animation.

Including the title in the original html is still supported.

Fixes some issues with margins and line spacing.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer,
_not_ a full super star committer.
