Tutorial sequence no longer includes feedback

Resolves #73
This implements the low-hanging fruit option, which was to simply remove feedback from the tutorial sequence, since it is not required.

It looks like the tutorial is now sticking at the 'Enter the incorrect answer' step. Choosing an image for the right side and providing a text description for the image will allow the tutorial to proceed, but choosing text for the right side will not.

Thanks for double-checking, I thought I ran through every combination but failed to do so when making some final tweaks. Every combination should be working now.

Tutorial stickage looks to be resolved.
