- Darken the header tab background to match the default editor
background color.
- Hide the distracting focus outlines for the editor and game canvas.
- Use a pure black background for the game canvas to better distinguish it
from the editor and provide a more neutral background.
- Use a bold font weight for the Start Godot editor button on the
loader page.
- Link to the web editor documentation on the loader page.
- Clarify what happens when clicking "OK" in the persistent data removal
warning dialog.
- Tidy up the HTML template by removing obsolete attributes.
We used to only persist specific sub-folder of /home/web_user/ when
running the Web Editor. This resulted in bad UX about default project
creation path etc.
This PR makes the whole folder persistent, move the zip preloading to a
different folder (to avoid persisting it), and automatically prompt the
user to import it if present.
