title: Laravel blade debug view name on error
body: <p>when there is some error in view, L4 shows a nice trace, but cached filename:
  open: /var/www/webpage/app/storage/views/1154ef6ad153694fd0dbc90f28999013</p>
  
  <p>howto during view-rendering-to-cache save view's path/name (in a comment or something)?
  Or better yet - to show it in the debug-error-page (its called whoops or something?)</p>
  
  <p>Thanks ;)</p>
