Self import plugin to use registered types

In Qt-Components framework some Enum types are registered in MeeGoPlugin class which extends QDeclarativeExtensionPlugin.
However, even registering these types in the plugin initialization, they are not recognized in the QML files inside the same plugin unless adding a self import.

Example (myplugin registers PageStatus):

qmldir:

plugin myplugin
Dummy 1.0 Dummy.qml

Dummy.qml:

import Qt 4.7
// commenting the line below will result in error:
// "Can't find variable: PageStatus"
import myplugin 1.0

Item {
    property int status: PageStatus.Inactive
}

For components, it's necessary to remove this internal imports, to avoid the same plugin to be loaded twice when using a different namespace externally (symlinks).
