If model has enum type, serialize its name to string in model, fixed camel case in model ToContentValues generating

Thanks for your fork, it helped me much.

Found some small issues, that prevented generating correct model class, so I needed to fix it manualy. 
1. Check, if model has enum type, add getting its string name.
Now it does in that way
cv.put(MovieTable.Columns.TYPE.getName(), type.name());
2. fixed generating ToContentValues in model, so no it can also process camel case and generates the same IDS as in Content
So it does cv.put(MovieTable.Columns.SERIES_ID.getName(), seriesId);
NOT cv.put(MovieTable.Columns.SERIESID.getName(), seriesId);
