commit 1382d09efadc900f7242c2e23482a9970eaf4f9b
Author: Ryan Scott <ryan.gl.scott at gmail.com>

    Remove unused XArrApp and XArrForm extension points
    
    !301 removed the `HsArrApp` and `HsArrForm` constructors, which
    renders the corresponding extension points `XArrApp` and `XArrForm`
    useless. This patch finally rips them out.
