Hotfix:
- added scrappedFromPosition (like in the android ListView implementation) to associate listpositions with scrapViews -> should fix https://github.com/huewu/PinterestLikeAdapterView/issues/8
Merge branch 'master' of yekretsam into upstream and modified them.

    Supported non scraped views for header correctly.
    Applyed yekretsam codes when view type counter is 1 too.
    Looked proper scrapView from top of scrapView stack.
