Subject: action: Create and use a different Logger for each action.
X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;p=matthijs%2Fprojects%2Fbackupninja.git

action: Create and use a different Logger for each action.

This logger is created using the action name as the logger name, so it
is included in the log messages.
