Setting `NoProgressBar` in `pacman.conf` produces warning

[christian-heusel]

Setting NoProgressBar gives the following warning, even though it seems to be a supported pacman option:

$ pacconf | head
warning: config /etc/pacman.conf line 35: unknown option 'NoProgressBar'
[options]
RootDir = /
DBPath = /var/lib/pacman

This was discovered because https://github.com/maximbaz/rebuild-detector uses pacconf: https://github.com/maximbaz/rebuild-detector/blob/d9a762b58ac5a8f7e85387ca75512ec18cf87854/checkrebuild#L37-L38

This has already been reported in #46 and fixed in 5d41cd5 on master, though no new release was made since.
