component AP gateway: fix handling of XMPP comments authors: the gateway was supposing that comments where emitted from PEP of author. While this is the case for most blog posts, it's not for comments. Instead the component is now using `author_jid` which is retrieved by XEP-0277 plugin, and reject the item if the auhor is not verified (i.e. if `publisher` attribute is not set by XMPP service).

#!/bin/sh

eval $(dbus-launch --sh-syntax)

# default, backend is launched in foreground
if [ $# -eq 0 ]
then
	exec libervia-backend fg
fi

# backend is launched with an explicit subcommand
if [ $1 = fg -o $1 = bg -o $1 = debug -o $1 = stop -o $1 = status ]
then
	exec libervia-backend "$@"
fi

# a whole command is specified
libervia-backend bg
exec "$@"
