Title: Updating to latest android-support-v4 and Android API level

I don't know if you get these type of Pull Requests often.
My app was using a newer android-support-v4 than ActionBarSherlock.
My app was failing to compile because NotificationCompat.Builder.build() was not defined.
I don't know if this would break any other uses of ABS, but I imagine the risk is either low or they can always go back to an older version of the android-support-v4 if they need to.
