Replaced ActionBar tabs with a styled PagerTabStrip which avoids the weird tablet styling of the ViewPager tabs
Lightened the tab background color
Darkened tab strip indicator color, skip loading blogs in ReaderBlogAdapter if they're already being loaded
Removed android:lines from the tab strip text style since it does nothing.
