1.1.0

• updated handling of a components lifecycle to match the of a custom element
  • the use of the initialize and destroy callbacks are deprecated and should not be used anymore from now on
  • three new callbacks were added to a components spec
    • created — a component/element was created. This callback is called once and the element does not have to be part of the document yet
    • attached — called every time when an element was added to the document
    • detached — called every time when an element was removed from the document
• changed the way gremlins.findGremlin() works. It does not return null or a gremlin anymore, as it's not guaranteed, that the component has already been created.
  gremlins.findGremlin() returns a promise now.
