New Development Version
Fix NPE on < 4.0. Closes #187
Fix attempting to add header view after being destroyed. Closes #186.
Add FLAG_LAYOUT_IN_SCREEN to WindowLayoutParams

This fixes problems on the Kindle Fire HDX and other devices where
the default window layout space doesn't include the status bars,
resulting in the header view being too low by the height of the
status bar.
Alternative fix for #246 NPE.
Updated to smoothProgressbar 0.3.3 and fixed gradle build errors
Don't use styles for AB, style the header in xml ...
