Tallscreen 0.3.0

New
- On Twitch, the Tallscreen buttons now sit in the video player's control bar, next to Studio mode and Fullscreen, where layout controls belong. The vertical stream button only appears when the channel actually has one.
- New option: switch to a Twitch channel's vertical stream automatically when it has one and your window is vertical. Off by default. Going back to the desktop site is never undone in the same tab.
- New icon.
- The "Smart" option now uses Tallscreen's own colours, with the same animation.

Fixed
- Twitch Studio mode (formerly theatre mode): Tallscreen now steps aside properly instead of resetting your hidden chat modules.
- YouTube: past streams without a chat replay no longer get an empty box under the video.
- YouTube: a live stream could load the replay chat instead of the live chat.
- Kick: the drag bar between video and chat gave the wrong height once the page was scrolled, and covered Kick's sidebar.
- The toolbar popup no longer scrolls on smaller setups.
- The Pro page button now reads "Manage purchase": Pro is a one-time purchase, not a subscription.
