title: how to set default prefix for routing in CakePHP 3?
body: <p>I am using prefixes for languages, I am not sure this is the right way, but I don't want to write custom routes for each of my controllers. I have 20 controllers by now (most simple).</p>
  
  <p>I have the problem that /nl/contact and /en/contact are trying to route to nl_index() and en_index(), which is fine for admin routing, but all controllers were programmed multi-lingually and using i18n, so they should use just index(), edit(), etc and not language_ in front of it.</p>
  
  <p>How can this be done? The reason I added these prefixes is that I can use the same controller and functions for more content. I am currently writing Configure.write language in beforeFilter for the languages based on first 2/3 characters of the url (/en, /nl).</p>
