Feedback Feature; Analytics Tweaks; Some Styling

@herany @okrg I create this feature on a branch in order to give you a chance to review it.
I think unsolicited feedback is super important in the early stages, so I created a really simple form to handle it.  If you have any suggestions for improvements, I am all ears!
I created a method to handles null checking of `analytics`, but this should move to a dependency injection at some point
