Command line interfaces

Command-line interfaces: added the option -quit:off to prevent exiting the Java VM in the event of a failure; instead, a RunTimeException is thrown. Useful when the command line interfaces are invoked from another Java application, for example ant, as it allows the calling application to recover.

When the -wrap option is used in XQuery, the serializer is now capable of generating an XML representation of a map, using nested elements to represent the entries in the map with their keys and values.
