Update network to support SSIDs with spaces (samtap#95)

The results from running iwlist through awk are tab delimited. By echoing with out quotes the tabs become spaces but then the cut messes up if there is spaces. By using quotes around $x the tabs are kept and cut uses tab as the default delimiter so no need to specify.
