Possible unwanted code and scripts

[CDuffers]

I'm working on some pull requests for minor tweaks on the import and export shell scripts and noticed the following code which I cannot find being used anywhere:

backup/emoncms-import.sh

Lines 42 to 50 in 9cfc5b8

	# Very old images (the ones shipped with kickstarter campaign) have "emonpi-28May2015"
	if [[ -z $image_version ]] || [[ "$image_date" == "emonSD-17Jun2015" ]]
	then
	image="old"
	echo "$image image"
	else
	image="new"
	echo "$image image"
	fi

It used to work here and was commented out some time ago:

backup/emoncms-import.sh

Lines 156 to 166 in 9cfc5b8

	# Start with blank emonhub.conf
	# if [[ $image == "old" ]]
	# then # Legacy image use emonhub.conf without MQTT authenitication
	# echo "Start with fresh config: copy LEGACY default.emonhub.conf:"
	# echo "cp $emonhub_specimen_config/old.default.emonhub.conf $emonhub_config_path/emonhub.conf"
	# cp $emonhub_specimen_config/old.default.emonhub.conf $emonhub_config_path/emonhub.conf
	# else # Newer Feb15+ image use latest emonhub.conf with MQTT node variable topic structure and MQTT authentication enabled
	# echo "Start with fresh config: copy NEW default emonpi.emonhub.conf:"
	# echo "cp $emonhub_specimen_config/emonpi.default.emonhub.conf $emonhub_config_path/emonhub.conf"
	# cp $emonhub_specimen_config/emonpi.default.emonhub.conf $emonhub_config_path/emonhub.conf
	# fi

And similar for export it has this code which isn't referenced anywhere:

backup/emoncms-export.sh

Lines 53 to 59 in 9cfc5b8

	# Very old images (the ones shipped with kickstarter campaign) have "emonpi-28May2015"
	if [[ -z $image_version ]] || [[ "$image_date" == "emonSD-17Jun2015" ]]
	then
	image="old"
	else
	image="new"
	fi

I propose that these code segments are no longer of use and should be removed to tidy up the scripts a little.

I'm happy to work on pull requests and some testing and wanted to get your thoughts before spending time on it. What do you think?
