Fix Bug #609508 - Support Out args as return object if possible

Fixes issues with in/out arguments
Better debug message (names the argument)
For calls that have 'out' arguments
a) If return is VOID - the return is an object, with properties set to the out values
b) If the first out argument is an object, then all the out values are set as properties on that.
c) still supports out_argument.value setting (previous way of doing this)
