Add support for custom (QVector<MyType>) Q_DECLARE_METATYPE in the repc

Hi,

In my current app I want to replicate a simple list of enums:

// MyRemoteObject.rep
  ENUM FeatureEnum{ Feature1, Feature2, Feature3  }
  PROP(QVector<FeatureEnum> enabledFeatured SOURCEONLYSETTER)

Currently it only works when I add:

    // Must use using alias otherwise  the <> create errors
    using QVectorFeatureEnum = QVector<MyRemoteObject::FeatureEnum>;
    Q_DECLARE_METATYPE(QVectorFeatureEnum )

to the generated rep files. This should be done automatically for custom QVector types or by embedding the Q_DECLARE_METATYPE code from above into the MyRemoteObject.rep file.

Currently only custom c++ imports are working with the repc. So the question is can we code that the repc recognizes QVector<FeatureEnum> automatically and inserts the necessary code by himself or do we code that the repc recognizes Q_DECLARE_METATYPE and using statements?

Cheers
