updated BUGs in general to remove older / fixed BUGs relating to the confusion of current/eids, etc.

update amendments in tables.sql to include job_id in entry_ammendment
added amend.py to move amendment-related code into its own file when we create a job (NewJob)
  and that job matches an amendmentType (via job_name or job_name:amt <- where amt relates to how we do a transform_image), then
  we enter a new EntryAmendment pa_job_mgr knows when a Transform job ends, and removes relevant EntryAmendment
files*.js use EntryAmendment data to render thumbnails with relevant AmendmentType
if a normal page load (like /files_ip), and there is an EntryAmendment, mark up the thumb, run the check jobs to look for completion of the job,
  removeal of the EntryAmendment and update the entry based on 'transformed' image

OVERALL: this is a functioning version that uses EntryAmendments and can handle loading a new page with outstanding amendments
  and 'deals' with it.  This is a good base, but does not cater for remove_files or move_files
