i3status doesn't distinguish between Idle and discharging battery.

At some point i3status on my computer stopped correctly displaying battery status while battery is idle. It is a really annoying bug.
I'm using gentoo linux.

I've looked into the code and discovered that i3status treats `Discharging` and `Not charging` states the same way.
Could you please considering merging this small patch to fix it?
This is small change causes i3status to display `status_unk` string when battery state is detected as `Not charging`
