Old versions cached full output to memory and only after that printed it
into log. This behaviour causes issues in case if operation stucks and
you would need to find the step at which it does. New check_output
method uses Popen directly and iterates over stdout lines
Also changed behaviour from merging stderr into stdout to separate
stderr logging.
Any other behaviour of the function must be the same.
Also changed GPG.key_import method to disable local signing since it
seems it is useless (and may break process in case if there is no
private key)
this also requires to move default configuration files to share/ahriman.
Thus the following features have been added
* default configuration is not stored in /usr/share/ahriman/settings
* package installed via PKGBUILD now copies files from /usr
* configuration class now fallbacks to default in /usr
In current workflow you need to run setup to run init (because of
repository name), but you need to run init before setup (because of
repository tree rights).
New solution just add `Repo.init()` method call to setup subcommand
after config reload to make sure that repository name has been applied.
In addition chown method as well as setuid method for check_output have
been added.
* Allow spaces in lists. This feature has been done in the way as shell
interprets arguments by using quotation marks
* Clear current content on reload
