Code review comment for lp:~victored/granite/contractor-wrapper

Here's a list of current Contractor users (From https://docs.google.com/a/elementaryos.org/document/d/1Ijsc57vYEHBZxVdM0fRgCuBX2NbdRDv1kuOj0OG75v4/edit#):

    ContractorMenu widget in Granite

    ContractorView widget in Granite

    Context menu of Pantheon-Files

    Maya, Scratch, Midori and elementary-flavored Simple Scan access Contractor via Granite convenience functions and rely on the fact that Contractor returns a string to be executed

    Eidete uses ContractorView widget from Granite, needs to be updated due to API break
