Add BatteryP a monitor for batteries
With this monitor is possible to set specific location where to retrieve battery information. For example: Run BatteryP ["BAT0","BAT1","BAT2"] [] 10 this will read the following files: /proc/acpi/battery/BAT0/info and /proc/acpi/battery/BAT0/state /proc/acpi/battery/BAT1/info and /proc/acpi/battery/BAT1/state /proc/acpi/battery/BAT1/info and /proc/acpi/battery/BAT2/state darcs-hash:20080316160115-d6583-efd35abf7a6a1a40fcb5f97ec430783f40b3221d.gz
