gambas 3c64df79b7 Namespace support continued. 
[COMPILER]
* NEW: Add the '-n' option that defines a default namespace for exported classes.
* BUG: The generation of '.info' file now uses the exported name of classes.
* NEW: 'EXPORT TO <Namespace>' exports the class as '<NameSpace>:<class name>'.
* NEW: 'EXPORT TO DEFAULT' now exports to the global namespace.
