Description:
Because $IWOPTS is not an array variable,

iwconfig $WIFI_INTERFACE $IWOPTS

where

$IWOPTS="mode managed essid $ESSID key $KEY"

will break $ESSID into multiple arguments if $ESSID contains spaces. Attached is a patch that allows $IWOPTS to be an array, so one can use

$IWOPTS=(mode managed essid "$ESSID" key "$KEY")

in a network profile, and netcfg will work correctly. Existing profiles where $IWOPTS is not an array will continue to work.

Additional info:
[my /etc/network-profiles/worldwireless]
...
ESSID='world wireless'
IWOPTS="mode managed essid $ESSID key $KEY"
...

[output of "netcfg worldwireless"]
...
iwconfig: unknown command "wireless"
...

Steps to reproduce:
1. In wireless network profile foo, set ESSID='spaced name'
2. netcfg foo
