Hide pageText if evaluates to false

[martijndwars]

This PR checks whether settings.inputs.pageText evaluates to true. If not, it hides the extra span in the pagination (which by default has the text "Pages: ").

The following configuration will then hide the "Pages: " span:

$('table#chats').dynatable({
  inputs: {
    pageText: false
  }
});
