Add generated Holo style overrides

Files were generated using http://android-holo-colors.com/ and
http://jgilfelt.github.io/android-actionbarstylegenerator

All of the themes_holo_custom.xml files were then manually edited to make
@style/holo_custom inherit from @style/Theme.Actionbar_custom and to
change android:textColorHighlight to use @color/primaryColor
