Inconsistent API in Partnership

[jochenberger]

This is a very minor issue, but it somehow feels strange this way.
Partnership.getAllAttributes() returns IStringMap whereas getAllSenderIDs() and getAllReceiverIDs return StringMap. I'd say they should all return IStringMap.
But maybe the methods should be deprecated altogether and replaced by getters and setters for each property, but I guess that's a separate issue.

One more thing:
there's addAllAttributes(IStringMap) but addSenderIDs(Map<String,String>) and addReceiverIDs(Map<String,String>), so different parameter type and different naming scheme.

Thanks for pointing that out Jochen. Indeed minor things, but still important :)
