Edit Book: Change the suggested prefix for bulk renaming of files depending on the type of files being renamed. Fixes #1514468 [Bulk renaming of non-Text files in the editor](https://bugs.launchpad.net/calibre/+bug/1514468)

Minor changes to the commit that actually implemented this
functionality:

1) List categories in only one place

2) Allow user to rename across categories -- although I can think
   of no good reason for this, I don't want to place an unnecessary
   restriction on the functionality.
