Add backgrounding functionality to net-profiles

Known from the DAEMONS syntax in rc.conf, it is now possible to start netcfg profiles in the background.
This fixes FS#23934 which was reported by Andrej Podzimek (andrej).

 ## Start a specific list of profiles on boot
 
-net-profiles allows you to start some profiles on boot. Specify the profiles you want netcfg to start in the NETWORKS line in /etc/rc.conf. For example:
+net-profiles allows you to start some profiles on boot. Specify the profiles you want netcfg to start (in this order) in the NETWORKS line in /etc/conf.d/netcfg. Prefix a profile with a @ to start it in the background. For example:
 
-    NETWORKS=(home mywireless)
+    NETWORKS=(@adsl @mywireless lan)
     
 To run on boot, add 'net-profiles' to your DAEMONS line.
