LinuxServer Changes:
Install unrar from linuxserver repo.
mylar3 Changes:
config: remove unused ALLOW_PACKS configuration options
These are not referenced anywhere, and the DDL definition overrides the
Torrents definition.
Furthermore, as they default to false, they give a confusing impression
of what Mylar will do by examining the config file, where you will see:
[DDL]
allow_packs = False
but Mylar will happily download packs regardless. (Guess who was just
confused by this while making my other pack-related change. :p)
