    Update Manage Roles link to be Inline Button

    This patch changes the Manage Roles link on the deployment plan
    page to be a button. It also moves it to be inline with all
    other main buttons on the page.

    Note that the Save and Cancel buttons when changing the number
    on nodes assigned to roles will remain floating to the right.
