UX improvements to livestream setting

[lucastbelem]

Most of our events are Sunday service livestreams, but we do occasionally have other events. So, I'd love to be able to set what the live page should look like from admin rather than Visual Code. Here is what I'm thinking:

• Title below video should match event title in livestream video settings.

• Add a checkbox for "show video carousel" in the livestream video settings. If checked, make it possible for user to select which carousel to choose. Also make the checkbox be checked by default and the "livestream videos" carousel be selected by default.

• Maybe "Livestream" becomes the place we manage central settings and we call it "Livestream Settings" and we create a sub-menu item and call it something like "Livestream Events").

• Livestream settings options:

• Set title for when we are not live

• Show "not live message" field for editing

• Show "add to calendar" checkbox

• Show "connect button" checkbox

• Set youtube id for not-live videos

• Other requirements to follow.
