* Use Varnish 3 from source tarball, newer and OS Varnish could not disable telnet authentication required by Carto
* Remove sources of varnish, gdal, /cartodb/.git when no longer needed in order to make image smaller
* Dropped Nokia and GMAP basemaps, they did not work
* Dropped schema trigger installation, it is no longer needed
* Configure Carto in Python and NodeJS
* Build assets
* Use self as asset_host, assets are hosted by nginx instead of rails
