remove min row # requirement when initializing collective.js.datatables

There's the hard-coded requirement in tablepage.js that says only enable DataTables when there are at least 4 rows. For users it's very confusing - they expect it to always be enabled.

It's a subjective matter anyway - choosing some min # of rows is matter of personal preference - so IMHO, this requirement should be removed. Just always enable DataTables JS.

Or, at least let's make the min count configurable.

But yes, it can really confusing users
