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

Added more entries

Write it out into canto-space instead

All output will now be logged to $LOGFILE using exec to redirect

Additional additions to .gitignore

The path to the file was not included so the check for exisitance/content was failing
