Report moderation

    - redaction marked with [...]
    - of report and comments
    - stores original data
    - uses a single form, on the report/_main view
    - requires additional permissions (user_body_permissions)
    - Hide report functionality
    - Moderation notification/contact form
    - Moderation writes to admin_log
Tests for moderation
Move bromley from report hiding to moderation

The feature to hide reports is still enabled, as it is used by other
`users_can_hide` bodies.  As we want to roll out moderation to Bromley,
in this commit we hide the functionality *only* for Bromley.  Of course
if we migrate those other users to this moderation method, then we will
need to make equivalent change to general template, and remove the
functionality from Report.pm.
refactor repeat code into get_email_template
Moderation - update-schema fixed and improved

[EmptyHomes] decommissioning tweaks

Merge branch 'emptyhomes-decommissioning-2014'
[EmptyHomes] remove custom text

Link is broken, and a variant of the text has been added to the
explanatory emails.
Update test for changes in 6eff7846.
Simplify z-index of banners.

Constrain the map in a position:relative to give it its own stacking
context. This simplifies these z-indices and prevents the elements from
floating above the main header. Fixes #673.
Allow multiple arguments to make_css.
[Hart] Remove unnecessary z-indices.

No longer needed due to core changes.

[EastSussex] tweaks after comments from ESCC

 - change front-page text
 - rename Category to Type
    By overriding report/new/category template snippet.  This is hacked
    in (including substitution of the "-- Pick a category --" text, as
    not sure how to simply do this as a cobrand-specific translation.
 - hide footer on mobile view
 - pothole field input and display
      This is a temporary request, which we hope will be superseded by
    full integration in due course.
      A command is documented in the cobrand to set the "extra" on the
    contact info for the Potholes category.  This is then displayed by
    the UI.  The default process_extras places it in extra, for
    potential future processing.
      As this is a temporary fix, we are calling this field
    "detail_size", as this is automatically included in "Details" and
    therefore also sent in the email.
      (This means that we may need to update data later on to call this
    "pothole_size" or similar in future?)
 - contrast tweaks (Via request from Matt Tooke at ESCC.)
   Not all handled precisely as he suggests:
    * spacing of button nav -- more or less as suggested, but tweaks for
    the <span> selected button, and reduced padding on non-frontpage.
    * sign-in buttons: fixed using CSS for .green-btn instead of adding
    HTML class throughout.
    * mobile-footer: edited <footer> css, as suggested by Dave Arter.
 - revert problematic CSS (breaks map report page)
 - Remove spurious "FixMyStreet" button
 - frontpage subheading wording
