Floating label alpha evaluation

[vadymhimself]

Fixed wrong alpha calculation for floating label.

    <com.rengwuxian.materialedittext.MaterialEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:met_floatingLabel="normal"
        app:met_textColorHint="#000"
        app:met_floatingLabelTextColor="#000"
        android:hint="Hello World!"/>

Expected result should be:

Actual result:

Fixed by correcting floating label alpha evaluation

Thanks - I hope this will be fast included.

@rengwuxian please include this. Right now it is impossible to have expected color on floating label.

When will this be merged? It is very needed because the library doesn't look good on dark backgrounds..
