• Fix v2.0.9 in order to make it "production-ready"

Full Changelog: 2.0.9...2.0.12

_{Side note: Using the defer-inst-via-detached-script branch for this release.}

^{This variant has most potential (out of defer-inst-via-systemd-timer, defer-inst-via-systemd-unit and defer-inst-via-detached script, which are their branch names), as it provides more degrees of freedom to specify the timing of the asynchronously called harbour-storeman-installer script, which turn asynchronously calls pkcon to install Storeman. OTOH, these additional possibilities also require more considering, fine-tuning and testing.}
