text: Title: Channel alias
  Body: If you have a channel called **articles/food/special** it will be accessible thought **http://...../articles/food/special** you may want to set an alias for this channel . (in the same way symbolic links works in FS)
  
  Lets say you have a content **articles/food/special/delicious.html**
  
  So, going to channel admin and setting.
  
  aliases: ['articles/specialfoods', 'specialfoods', 'deliciousfoods']
  
  The same content will be acessible throught.
  
  **articles/specialfoods/delicious.html** or **specialfoods/delicious.html** or **deliciousfoods.html**
  
  as it is the same content, all the pages will have its **canonical_url** set to the real channel url **articles/food/special/delicious.html**
  
  If the alias name conflicts with a real channel name it will have low priority (useful when you want to unpublish a channel and put another one in the place)
