Error handling during import/export

[Google Code Exporter]

The interfaces KeyValueImport and KeyValueExport do not allow their convert
() method to throw an exception. I think that it is crucial that these 
methods can report conversion errors back to Jaql (w/o using runtime 
exceptions), either using declared exceptions or a return value.

Exception handling needs an overhaul in general. This is one of the items that 
will 
be addressed.
