ensure variable names are unique within a group [1462]
Fix for non-unique ADDE descriptor comment strings. [1458]

This requires VisAD commit "c42fe9158f393957936115b97cae5d69a3f3a63b"
or later! I've already updated visad.jar on pappy, so everyone should
be able to get the correct version once I rebuild the nightly.
changes to "annotate" function: changed 'justification' to 'alignment', reversed the meaning of
left/right and top/bottom, added error checking for alignment keyword,
better labels in the legend for annotation controls
Fixed assumption of unique comment strings (again) [1458]
getLocalADDEEntry now returns correct type [1303]
