Allow user to copy/paste case list columns

For example if you put a really long ID Mapping in the case list, but you also want it in the detail screen, you can now click on the ID Mapping row, Ctrl-C, navigate to the detail screen tab, click on the row below which you want to insert it, and Ctrl-V. To insert at the beginning, click on the header. User sees the built in "selected" browser affordance when clicking on a row. In ID Mappings in particular translations in multiple languages are maintained. (No extra effort, was just an extra thing I checked.)
lost your way @dimagimon?
