1-Base hardcodes the status bar color

[jimgswang]

In 1-Base v21/styles there is a line

<item name="android:statusBarColor">@android:color/black</item>

When we try to do the first step here at

The status bar color on lollipop devices will not be the blue shown in the screenshot but black instead. Commenting out the above line will result in the correct behavior.
