Renames 'canto_weekly.log' to 'canto_weekly_update.log', and routes it to the new sub-folder 'logs' 

a) changing docker ps search for DOCKERNAME variable
b) removing . from CURATEDPAPERLISTFILE variable
c) changing JSONARCHIVE variable from "import-fbrfs_json_$(date +"%Y-%m-%d")" into import-fbrfs_$(date +"%Y-%m-%d").json

Changed echo to log

This reverts commit 8da0f998

changing docker container image to pombase/canto-base

- Adding missing fi
- Added missing [[ & ]]

- Chaged name of config file dir to camto_support to prevent clash
- Added missing quotes for variable

- Added function check of db in canto_done file has changed since last run. If not then restart Canto and exit.
- Tidied up code ordering to make it more logical
- Create data folder to store some files to keep things tidy. It be sensible to put fbrf_input_list.tsv in there as well.

Improved retry loop
Added function to restart canto. This allows it to be called during a normal exit or if the rety loop fails
Converted tabs to spaces

JSONIMPORTFILE is defined as /import_export/import-fbrfs.json which works when relative to Docker. When referencing the file outside of Docker it needs to be prefixed with . for the script to find import-export in the current working directory.
Fixed incorrect datestamp for JSONARCHIVE

Fixed logic issue with creating archive directory
Shortened timestamp on archived files as dd/mm/yy is enough granularity
Fixed issue with JSONARCHIVE being copied with correct filename

sha binary is called sh1sum not sha1
Fixed refererence to OLDHASH not SAVEDHASH

Reworked logic to test if contents of import-export has changed by using sha hash
Backed up files to archive
