Exceptions reveal sensitive information

I noticed that exception's shows "sensitive" information. Search do not work properly as well (or you just disable search for PHP) :)

```
Template is missing
Missing template public/404.html with {:locale=>[:en], :formats=>[:html, :text, :js, :css, :ics, :csv, :png, :jpeg, :gif, :bmp, :tiff, :mpeg, :xml, :rss, :atom, :yaml, :multipart_form, :url_encoded_form, :json, :pdf, :zip], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee, :rabl]}. Searched in: * "/home/emoticode/app/views" * "/"
