Core Data pt 2

Updated almost everything for core data usage as well as fixing
prefernce saving. The only Object that needs any touching up is
RunStuff. I also made a bunch of small changes like showing the current
shortcut when you load the tableview.

Not the best commit notes, but hey, Im tired.
