[PYOPENMS] support for aliases in StandardTypes.h

I wanted to wrap the missing aliases declared in *StandardTypes.h* and discovered that *Chromatogram* exists in 

  * *OpenMS* namespace as defined in *StandardTypes.h*  
  * and in namespace *OpenMS::Interfaces* as defined in *OpenMS/INTERFACES/DataStructures.h*. 

The current implementation wrapped the latter as *pyopenms.Chromatogram* instead of *pyopenms.Interfaces.Chromatogram*. I fixed this and two other wrong assignments before adding the aliases from *StandardTypes.h* to pyopenms.
