Add parameter to _ebo keyword that just shows checkboxes

[ivojolo]

For custom-coded bulk processes, I've stopped coding my own checkboxes when KTL is available, as KTL already does a lot of the heavy lifting with checkbox generation.

However, on many of these tables, I don't want to enable any of the bulk operation options to the user (delete, copy, edit, action).

What I've been doing in these situations is using one of the _ebo keywords but hiding the buttons from the user. This isn't ideal, and, it'd be great if there was a generic _ebo keyword that just generates the checkboxes.

I couldn't find any existing keyword/method of doing this with KTL. Would be nice! Thank you.
