Fixed manual data saving, added Change Description dialog option to Queue Saver
Changed queue layout's header text to inform user to press-and-hold data sets to edit them.  I personally think this beats changing to the iOS "Edit Mode" table view.  Also got rid of the "Select Experiment" button if your data set was recorded with an initial experiment.

Added UITextField validation across all View Controllers and Alert View dialogs for every text field in the application.
