Directive hooks

[mbraint]

Case:
When I create custom directives, I thinked that 'update' and 'componentUpdated' hooks of directive will be call when component or children updated, but the hooks works only when updated vnode. I think will be useful add this informaition to docs.

Actually desctiption:
#Hook-Functions
'update: called after the containing component has updated'
'componentUpdated: called after the containing component and its children have updated.'

Expected desctiption:
'update: called after vnode of the containing component has updated'
'componentUpdated: called after vnode of the containing component and vnodes of his children have updated.'
