add a file's title & property drawer's ID

[Wonko7]

This seems to do what I want, but I'll be playing with it in the next few weeks, I'll probably find bugs and update this.
In no rush to merge, but I'm open for feedback.

@Wonko7 thanks for working on this. My main feedback so far is that both of the new functions are almost identical to org-sql--insert-alist-add-file-properties so it makes sense to consolidate them.

These additions would also need to be documented, which I can help with unless you also want to take a stab at that.

I'll take a look.

also the code is unfriendly to files missing an ID, I'll push something at some undefined but hopefully soonish point in time.
