Added missing copyright notice in RemoteFeedbackView.h/.m
Corrected a couple of 'floats' to 'CGFloat'
Removed Carbon.framework from project, it's not needed at all.
Removed CoreData.framework from project, as it's entirely unneeded
Incremented copyright year to 2014
Renamed all ivars (except IBOutlets) to start with underscore

As per Cocoa convention.  This touches many files, but should be a pretty safe change
since I used Xcode 5's refactor tool to do the renames (and doubled checked it).
