Change required for JPype 0.7.0

[Thrameos]

This deals with the startup. There are two additional differences.

def _handle_sql_exception_jpype():
    import jpype
    SQLException = jpype.java.sql.SQLException
    exc_info = sys.exc_info()
    if issubclass(exc_info[1].__javaclass__, SQLException):
        exc_type = DatabaseError
    else:
        exc_type = InterfaceError
    reraise(exc_type, exc_info[1], exc_info[2])

Exceptions in 0.7 now catch the exception type directly rather than as part of the arguments to the exception.

I think I've already merged/integrated the changes of this PR. Thanks @Thrameos !
