[Paraview] Read an IntVectorProperty

[Utkarsh Ayachit]

For information properties to work, one needs what's called "Information 
helper" objects. These are instances that know how to obtain the given 
information from the server side VTK object. In your case, all you need 
is to add  <SimpleIntInformationHelper/> to the XML as follows:

<IntVectorProperty
                     name="ValidExeInfo"
                     command="isExecutableValid"
                     information_only="1">
       <SimpleIntInformationHelper/>
       <Documentation>
           This returns whether a valid executable has been selected.
       </Documentation>
</IntVectorProperty>
