Change default behaviour of ignore_download_error to false

[rhtenhove]

The default behaviour is to ignore download errors. In my (quite regular) setup this causes adsorber to not apply anything, because it runs at system startup with systemd, and the wifi doesn't connect that fast.
This results in an empty hosts file, and thus nothing gets blocked except for what's on the blacklist.

When setting ignore_download_error=false in /usr/local/etc/adsorber/adsorber.conf, it still proceeds after a download error when running adsorber update. So it seems the setting is ignored either way.

Hello rhtenhove,

Thanks for reporting!

Sorry for being late, been on vacation.

I could reproduce your issue, im onto fixing it.
Also I will change the default ignore_download_error to false as you suggested, because it makes more sense actually.

Cheers
