remove dependency on sabnzbd default config and use sed for editing

Because initool cannot parse double-nested categories, sed is used
instead to edit sabnzbd.ini values. It also appears that SABnzbd will
keep any initial values written to sabnzbd.ini and then add any missing
keys with their default values. Therefore, we can just generate the bits
of config we need and let SABnzbd do the rest on its first run.
