VS Code has a short delay before writing storage (probably to queue up
rapid changes). In the web version of VS Code this happens on the client
which means if the page is reloaded before the delay expires the write
never happens.

Storage updates are already promises so this simply returns the promise
returned by the delayer so it won't resolve until the write actually
happens.

Fixes #2021.

Add initial support for opening files / folders in running code-server instance.

Current limitations:

- unable to open a file in a new window, only folders
- unable to use addMode feature
- others...

Mostly to match everything else.

Mostly so the base URL resolution code can be shared.

The broken symlinks cause nfpm to fail.

The postinstall uses rimraf so it needs to exist in the final build.

It can still be used to check for updates but will not apply them.

For now also remove the update check loop in VS Code since it's
currently unused (update check is hardcoded off right now) and won't
work anyway since it also applies the update which now won't work. In
the future we should integrate the check into the browser update
service.
