Campagnes at boost-project.com are no longer working (blank pages).
example: https://www.boost-project.com/de/charities/2774

Campagnes are now at wecanhelp.de:
Example: https://www.wecanhelp.de/441003001

With next API spec we should mark "boost":

as "depricated" (i do not know how to archive that in json specs) and add "wecanhelp" as a new provider to the enum.
