Added NNWTableViewCell; a base class for cells with the NNW selection color.

Defined a semantic color for the selection color which is identical to
netNewsWireBlue.

MasterFeedTableViewCell and MasterTimelineTableViewCell now subclass
NNWTableViewCell and no longer directly customize their selected background
view.
