Fixed Batched Thread Update can't set prefix to empty

[Xon]

Affected version

2.0.9

The Batch update threads function can't actually set prefix to empty (ie 0) because the applyInternalThreadChange function skips prefixes with a false-like value, and getActionValue returns null if the prefix_id is falsy.

This dialog should be more like the front-end where setting a prefix requires a "Apply prefix to selected threads" checkbox to be selected.

Technically, this is working as designed. The absence of a value here is designed to indicate that no change should be made to the prefixes of the selected threads.

That said, why not?
