Added Logging Category support to QML

New Logging Categories can be defined by using the
LoggingCategory type and define a name for the category

When the id of a valid LoggingCategory is provided as
the first argument to console.log and friends the
LoggingCategory is used instead of the default "qml"
LoggingCategory

[ChangeLog][QML Elements] Added a LoggingCategory type and added support
for it to the console object
