- removed deprecated code from RASocket
- allow more than one login at a time on the RA console

- removed deprecated mangos_string entry

Thanks to:

    players were connected  [poll() vs select()]
- caeruleaus for adding windowsbuild support
- vladimir for suggesting a different thread starting order
- fdb_ for suggesting SOAP in the first place
