Reference/references editor: Display all available options when threshold is 0

[lorenzulrich]

Description

When using a reference editor for taxonomy/categories, there are situations where you only have a bunch of nodes available for selection.

Currently, the editor has a threshold option with a minimum of 1, so you must at least type one character.

I suggest also supporting 0 as an option which will display all available options on entering the field.

Things to consider

• What happens if other than excepted, there are many (hundreds/thousands of) nodes available? In this case, this could break the browser rendering. Do we need to define a maximum of results displayed initially or falling back to a higher threshold in this case?

TMS.Select could be good an inspiration @lorenzulrich I like the ability to use it for reference (single) and references (multiple) too.

Maybe a limitation by a maximum value would be nice :D

I would also consider using TMS.Select. Perhaps it would be nice to have this kind of editor in the core

After having used TMS.Select on numerous occasions, I can live with this. Maybe integrating it to the core could be a good idea?
