Services spawn

It took some time, but i've managed to fix it for windows. Also, hopefully there will be no more zombie processes.
Tested on Debian and Windows 7, afaik everything works as it should.
It's not really safe to rely on this, but i can't think of anything better. On the clean system it should be fine, otherwise the user have to remove the acestream.port file manually before starting aceproxy for the first time.
