Updated the material library back to alpha03 version

The aforementioned fragment has fixed issue with layouts being oversized on API21 (maybe a bit lower and higher as well, did not test) which was notable on homepage.
Unfortunately it deprecated most of the logic behind hiding of the top action view. Since it inherited and overridden the functionality from HideBottomViewOnScrollBehavior it no longer called the old methods and so the whole class was rendered _useless_. Fortunately we didn't need the whole backing implementation so the parent class was changed to the bare minimum. Hopefully this incident will not repeat.

Thanks goes to material team for introducing breaking changes in feature update.
