cobrand file with geocoder etc config

also, make readonly, disable photos, questionnaires, never
hide old pins

Fixes #701
add in more or less vanilla base styles

change default colours to black and white
remove unwanted items from navigation

basically everything bar report and help
add template for updates with only required elements

remove login, name made public, photo upload, alert sign up
add in report display template

removing so much that we might as well copy the template, especially
as we need to change the header include.
Removed from default:
    most of shadow wrap
    RSS
    list of updates which are not public
plus Report -> Clinic
Remove subscribe to updates link from around page
split out RSS link tag to it's own template

makes removing RSS from cobrands much easier
blank header_rss template for ZeroTB

we don't want any RSS feeds for the site so disable
