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.

== Why is this an issue?
The ``++match++`` statement should be used only to clearly define some new branches in the control flow. As soon as a ``++case++`` clause contains too many statements this highly decreases the readability of the overall control flow statement. In such case, the content of the ``++case++`` clause should be extracted into a dedicated method.
=== Noncompliant code example
With the default threshold of 5:
[source,scala]
----
myVariable match {
case 0 => // Noncompliant: 6 lines till next case
methodCall1()
methodCall2()
methodCall3()
methodCall4()
methodCall5()
case 1 =>
// ...
}
----
=== Compliant solution
[source,scala]
----
myVariable match {
case 0 => doSomething()
case 1 =>
// ...
}
// ...
def doSomething(): Unit = {
methodCall1()
methodCall2()
methodCall3()
methodCall4()
methodCall5()
}
