Title: Dsc 305

This request completes the first part of the dsc-305:
- provides a regenerate access copy button on show work page (according to biz rules) which allow regeneration of jp2 and thumnail for that work.

- schedules the image copies regeneration job.

The actual execution of the image regeneration job step is yet to be done.
