Remove external asset dependencies

[amercader]

CKAN is pulling a number of resources from external locations. This causes problems when connectivity is limited and you have to work locally. Maybe some of them cold be moved to CKAN source to avoid external requests.

Quick search:

These are all images and all from assets.okfn.org items and of such as standard/generic nature they are not worth bringing in-house. If this causes problems for local dev then just add an /etc/hosts for assets.okfn.org that is local or /dev/null like.
