Spinner for recording length working
Keep step 2 enabled once the user sets up to prevent the disabling of the button when leaving the main activity, e.g. going to step 3 and going back.  Step 2 is then disabled after recording has finished once, then the user must set up again.
Manual informs the user if experiment fields couldn't be pulled due to a lack of internet connectivity
Changed the API's isConnectedToInternet call to use Apple's Reachability class, with some slight modifications.  This way we are no longer relying on connecting to a 3rd party arbitrary website to determine connectivity.
Added menu option to Automatic for media
