wineclipsrv runs as a daemon ; fixes bug #323

[jasonp]

Here's my first patch submission, so anything that is odd or should be fixed 
please let me know. That goes for either how I've submitted it or any coding 
issues.


Log Message:
wineclipsrv runs as a daemon (closes stdout/stderr, no 
controlling terminal, session group leader). Prevents wine from hanging on 
open stdout/stderr (bug #323)
