retrieving mac address on non-english locale fails

[Patrick Brueckner]

net responsibility uses ifconfig to get mac-address for interfaces.
when used on a non-english locale, grep fails, since it doesn't find the required keyword (HWAddr).

Forcing the command to run with the english locale fixes this problem.

Thanks Patrick! Finally this bug is solved.

For you who didn't follow:
Open /usr/share/net-responsibility/lib/options.rb as root to edit. Find this line:
IO.popen("ifconfig -a | grep HWaddr | cut -c39-") do |mac_addr|

Replace it with this line:
IO.popen("LC_ALL=en_EN ifconfig -a | grep HWaddr | cut -c39-") do |mac_addr|

That should do the trick.
