/*
field_generator power level display
The icon used for the field_generator need to have 'num_power_levels' number of icon states
named 'Field_Gen +p[num]' where 'num' ranges from 1 to 'num_power_levels'
The power level is displayed using overlays. The current displayed power level is stored in 'powerlevel'.
The overlay in use and the powerlevel variable must be kept in sync. A powerlevel equal to 0 means that
no power level overlay is currently in the overlays list.
