Visual refresh for submission form at waitlists directory

I made some visual updates to submission form (currently free) for my waitlist directory.

1) Added accordion / open close for form sections. I hope this makes the form less overwhelming. Still, some tweaks are needed, but hey. It's BiP. I will get to them.

2) No more emoji madness. I'm unsure about the colored backgrounds, but they're at least better than emojis. I might switch them to light gray and keep only stroke colors.
