Make sure that includes are always surrounded by empty lines (#2270)
When an include is not surrounded by empty lines, its content is inlined
on the same line as the adjacent content. That can lead to broken tags
and other display issues.
This PR fixes all such includes and introduces a validation step that
forbids introducing the same problem again.

== Sensitive Code Example
----
<a href="http://example.com/dangerous" target="_blank"> <!-- Sensitive -->
<a href="{{variable}}" target="_blank"> <!-- Sensitive -->
----
== Compliant Solution
To prevent pages from abusing ``++window.opener++``, use ``++rel=noopener++`` on ``++<a href=>++`` to force its value to be ``++null++`` on the opened pages.
[source,html]
----
<a href="http://petssocialnetwork.io" target="_blank" rel="noopener"> <!-- Compliant -->
----
== Exceptions
No Issue will be raised when ``++href++`` contains a hardcoded relative url as there it has less chances of being vulnerable. An url is considered hardcoded and relative if it doesn't start with ``++http://++`` or ``++https://++``, and if it does not contain any of the characters {}$()[]
