--app-name should set the page title

[code-asher]

Will need to add a variable to the HTML files to set the title to the app name (login.html, error.html).

And will need to patch for the VS Code HTML (workbench.html, workbench-dev.html) although not entirely sure how the titles there are set.

Would this override the whole page title (my personal preference) or just the suffix (I suspect the path of least resistance)? This is what my browser tab bar looks like with 3 different projects open:

The actual titles of each are:

README.md - workspace - code-server
README.md - workspace - code-server
README.md - workspace - code-server

Due to limited horizontal space, the code-server portion of the name (presumably what would be changed with --app-name if something more isn't done) isn't actually visible.

What I would like to see by setting --app-name environment variable on each instance would be:

Alternatively, perhaps just naming like the following would still leave the extra info but make --app-name more meaningful:

<--app-name> - workspace - README.md

This way, when truncated the --app-name takes priority but you can still see the filename and opened directory if you have vertical tabs or mouse-over.
