SessionHero final feedbback

sessionhero-final-feedback

Findings:
- Users had minimal feedback:
-- want to see password rules before submitting the registration form
-- want to see something letting them know that the sessions were loading when they 1st load the app (sometimes there's a delay)
-- want the option of _not_ having to login to add comments
-- needed feedback when clicked on stars to add/remove session from their schedule


I added:
- feedback on password rules before submitting the registration form
- a loading indicator and message that the sessions were loading when there was a delay in loading the sessions page
- an updating indicator when adding/removing a session from schedule

I also changed the demo login from demoUser, demoUser123* too testUser, testUser123@ because the asterisk was ambiguous.
