Merge branch 'develop'

* develop:
  works :)
  looking way better
  we can use remove instead of empty because the convention is to wrap the controller's view with one  DOM element
  getting closer
  adds <sections> as top element in many templates (in which that makes sense), adds some answers to the FAQ and fixes parentElement and view setting in #onTemplate:
  there is a mess with view and parentView, that's why isn't working yet
  closer..
  controllers knows a parent and the html element from which they have to be appended on render
  adding parent to controllers so they can reflect on its rendering state and who's the dom element to be appended into
  adding (sub) cotrollers to any controller, StuffController now maintains its children, needs to implement its proper rendering
  introducing StuffWithEch and Stuff so two different styles of composition are shown (each doesn't work but is not the coolest)
  clean up
  wooooooooorks!
