Improve logic of TV names ending with _select

[hugopeek]

All tv's with _select in their name should change to _id. Focus on the output here (placeholders in elements) instead of the input.. That feels more logical. Can something feel more logical? Better to restrain it to using ID.

Anyway.. Nothing is using it yet, so adjust while you still can!!

Affected TV's:

• author_select
• client_select
• contributors_select
