Add Annotations to Calculation Properties (SSAS Multidimensional)

[pavelsinkevich]

In VS2015 the "Calculation Properties" window allows to edit "Display Folder", "Associated Measure Group" and "Description". Please add the possibility to add/edit Annotations. SMO class Microsoft.AnalysisServices.CalculationProperty has member Annotations, so adding it to Calculation Properties window should be possible.
