This commit adds a new request to the FileSystemAccessServer
endpoint, allowing the clients to get read-only access to a file
without getting a Dialog-box prompting the user for access.
This is only meant to be used in cases where the user has asked
specifically to open a file through the command-line arguments.
In those cases, I believe it makes sense for the read-only access
to be implicit. Always prompting the user gets a bit annoying,
especially if you just quickly want to open a file through the CLI.
The new request name has been made extremely specific to make sure
that it's only used when appropriate.
