Please, add additional input fields in File field.

Hi!
I'm sure we should have more input fields in File field:

Hello

- version ? yes ... but ... this should be done properly (see below)
- custom 1, custom 2, yes ... but ... this should be done properly (see below)

**About Version**
besides version number property
- there should also be a "previous FILE ID" property
so that to create keep track of the previous file and create a version chain of them

**About custom**
besides custom 1, custom 2 properties
Inside configuration of every file field, the custom 1 and custom 2 will get specic labels
thus we will get appropriate labels for them when
- when we edit a file via item form
- when we view a file via item / category view

only file manager will call them "Custom 1" and "Custom 2"

I have opened a new issue
github.com/FLEXIcontent/flexicontent-cck/issues/743

But before the above we need to also show the download history / download stats in backend
(which we already log (using very little DB space) since v3.0.x)

Thank you.
