Add docker actions, arr profile enforcer, monitor caching, and web file symlink

Web files now served via symlink to the git repo so git pull changes survive
reboots without rebuilding the txz. Also includes: docker pull/rebuild/restart
with live log streaming, arr_profile_enforcer for Sonarr/Radarr quality
profiles, monitor page cache fix (background writer now in cron), and
ARR_KIDS/SONARR/RADARR profile name vars in master.conf.
