Doc: Various fixes to Qt Audio Engine documentation

-fixed \since to "\since 5.0" (Qt version 5.0)
-made a \qmlmodule page so the list of related classes are automatically
 listed
-made changes in the Qt Multimedia documentation to link to the
 Qt Audio Engine documentation

+
+Qt Audio Engine is part of the \l{Qt Multimedia} module. Qt Audio
+Engine provides types for 3D positional audio playback and content management.

+The QML types can be imported into your application using the following import

 \section1 Qt Audio Engine Features
 
-Qt Multimedia includes the \c QtAudioEngine QML module for
-providing 3D positional audio playback and content management.
-
-QtAudioEngine enables developers to organize wave files into discrete \l Sound with different
-\l {PlayVariation}{play variations}, group sound controls by \l {AudioCategory} categories and
-define \l {AttenuationModelLinear}{attenuation models} and various 3d audio settings all in one
-place. Playback of \l {SoundInstance}{sound instances} can be conveniently activated by in-app
-events and managed by QtAudioEngine or controlled by explicitly defining \l SoundInstance
-for easier QML bindings.
-
-To access these QML types import the
-\b{QtAudioEngine 1.0} module.
-
-\qml
-import QtQuick 2.0
-import QtAudioEngine 1.0

-AudioEngine {
-//...
