Update so that statistics can be plotted correctly

Update so that statistics can be plotted correctly

util/stats/stats.py:
    Changed some stuff for graphing purposes:
    full_cpu is now full0
    frequencies are now s,m,f,q not s,6,8,q
    L2 is now l2
    etherdev is now etherdev0

    May want to consider fact that NAT box should be the sum of etherdev0 and etherdev1 (not in script yet)
