## Issue
When "Upcoming livestream" appears in a list, infinite scroll stops working.
## Cause
The difference between `mainEl.getBoundingClientRect().bottom` and `window.innerHeight` became slightly greater than 0.5, so it was deemed as "haven't reached the bottom".
## Change
Coincidently, I've been wanting to make the inf scroll load earlier (instead of after reaching the absolute bottom) to make the experience smoother, so added a 200px threshold, which is roughly the height of a tile. This gets us the new behavior while also fixes the original problem.
* Test out a horizontal scroll for upcoming (tile only for now)
* - add support for list layout
- add following label on home page
- clan up css and naming conventions
* Update header type + show only if scheduled streams are showing
## Issue
Closes 627 account header doesn't refresh on sign up / log in
## Changes
Looking back at "[Header] Changes, fixes and improvements (#493)", noticed that old code was looking at `has_verified_email` instead of just checking whether an email exists. So, restored original code.
This does have a side-effect of the Logout button not showing any email address underneath it immediately after sign up (with the flow cancelled). But I vaguely recall it was that way previously. A refresh cleans it up.
Perhaps another `user/me` when leaving the Sign Up page can make everything in sync, but this PR simpler to test.
* Add a setting to hide scheduled livestreams from home/following
* Add a hide button in the scheduled stream header.
* Fix typo + make sure pref is synced
* Update publish form when editing livestream + update to radios for liveststream release time
* Fix bug where upload tools may remain visible upon switching upload type, even when no option to upload is available.
* move publish source state up, when editing livestream only show scheduling option when source is none.
* Reset any set release time if switching to live stream mode.
* Update date/time cmpnts to reset any chnages they made on umount. Update schedule date/time cmpnt to clear release time when selecting anytime option.
* Additional filtering of internal tags
* Default to replay view when editing a liveststream
- Query for that tag in the upcoming section
- Improve special tag organization
- Filter out the internal tags in the UI
- Add missing types to publish state
