Fixed data exports, added pid and id fields, added generate actions

[aOelschlager]

This pr changes the missing media view configuration file. I've added csv data exports for all of the media types checked for missing media. I've included the pid and content id fields for each media type view. I've added generate derivative actions to the media type views that are missing derivatives that are generated.

To Test:
Make a fresh starter site using this pr.
Add repository items and media.
Delete some of the media.
Choose the missing media view that makes sense for the media you deleted.
Select one or more models and click apply.
Download the csv.
Select one or more rows to perform derivative generation on and click apply to selected items.

Tested - it works! Looks great. The Actions there are really useful.
