Subject: Also pass csync logs through QMessageLogger
X-Git-Tag: archive/raspbian/3.16.7-1_deb13u1+rpi1~1^2~733
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=cc9680c1e870e09bad555026e23e5f5c63d950d4;p=nextcloud-desktop.git

Also pass csync logs through QMessageLogger

This allows using logging rules and custom message patterns with csync.
This also pass the a relative verbosity to the message logger.
