comment in downstairs/src/lib.rs proc_frame() is wrong

[leftwo]

in downstairs/src/lib.rs method proc_frame()

    /// Handle a new message from the upstairs
    ///         
    /// Returns `true` if the message was evaluated, `false` otherwise, or an
    /// error if communication failed.
    async fn proc_frame( 
        &mut self,
        m: Message,
        flags: &DownstairsFlags,
        reqwest_client: &reqwest::Client,
        dss: &mut DsStatOuter,
        region: &mut Region,
    ) -> Result<WorkResult> {

We now return WorkResult
