Nightly fix 2.3.8 to account for YouTube's class changes to the thumbnails on the sides.

Updates to match new changes made by Youtube to the UI, some spelling mistake catches, a fix to the toggle buttons in the menu, more un-rounding, including un-rounding parts of shorts..

Updates were added to work with new changes to the YouTube UI CSS. Also collection stacks are now un-rounded.

Minor update to match CSS code on YouTube main player with new location of rounded corners code placement.

Switched default "Actions Space %" setting back to 5%, most other changes were made to code and did not change settings or looks.

Updated to Manifest V3 and added an explanatory page on install to explain how to provide the proper permissions. Moved additional customization settings to the popup page.

Un-rounded more sections and added numerical option to revert number of videos per row on the homepage.

Major changes made to the user experience and underlying code. Most settings have been migrated to use storage and are controllable from the new popup page. In addition, new settings have been created, returning more items to their old look. Almost all injected code is simply stored in css files which are appended to the page instead of being built live from strings increasing readability and adding simplicity.
