This commit places the email CSS into the `style` tag located in the
`head` section. This resolves the issue of being unable to apply
certain CSS styles that cannot be inlined, such as media queries and
pseudo-classes.
This reverses the policy that was set, but incompletely enforced, by
commit 951514dd7d. The self-closing tag
syntax is clearer, more consistent, simpler to parse, compatible with
XML, preferred by Prettier, and (most importantly now) required by
FormatJS.

We make some specific cases of tags use 2 space indents.
The case description:
* A tag with opening tag spread over multiple lines and closing tag
on the same line as of the closing angle bracket of the opening tag.
* A tag with opening tag spread over multiple lines and closing tag
not on the same line as of the closing angle bracket of the opening
tag.
Example:
Case 1:
Not linted:
<button type="button"
class="btn btn-primary btn-small">{{t "Yes" }}</button>
After linting:
<button type="button"
class="btn btn-primary btn-small">{{t "Yes" }}</button>
Case 2:
Before linting:
<div class = "foo"
id = "bar"
role = "whatever">
{{ bla }}
</div>
After linting:
<div class = "foo"
id = "bar"
role = "whatever">
{{ bla }}
</div>
