Fix QML import paths in Qt resources.

Allow adding qrc: urls as import paths.
Store an import path of the form :/import/path as qrc:/import/path
which is expected by other parts of the code.

Update documentation for QQmlEngine::addImportPath() to explicitly
state what types of paths are supported.

Add auto tests to check that importing a module from a Qt resource
works.
