Qt Quick documentation fix: Fix the QtQuick and QtQml documentation

Umbrella task:

Qt Quick and Qt QML modules need to be sanitized and have content.

Both modules:
-sanitize the QML types and the basic types (enumerations, var, int, date, and so on.)
-make sure that the QML types have the proper import (both use QtQuick 2.0)
-enforce the proper terminologies
-use the proper documentation style
-use the QML module identifier

Qt Quick:
1)Add these types

• color
• font
• vector3d

2)sanitize the types (elements) with the proper style:

• needs \brief
• needs proper title (No "Using", "QML States", and no "Overview of" or "Intro to") There should only be ONE "Introduction to:"

3)sanitize the Qt Quick module page (http://doc-snapshot.qt-project.org/5.0/qtquick-module.html) Should link to the QML interface. Search for \qmlmodule
4)Add a landing page (QML/JavaScript + UI implementation + tools)
5)Create overviews (ask Jerome Pasion)

Qt QML:
1)Sort the list of types in Qt QML and list their import statements
2)Sanitize the types and the classes with the proper style:

• needs \brief
• links work

3)sanitize the Qt QML module page (http://doc-snapshot.qt-project.org/5.0/qtqml-module.html) Search for \qmlmodule
4)Add JavaScript related content
5)Create overviews (ask Jerome Pasion)
