CSW Harvester URL must be URL-decoded

[heikki]

When adding or updating a CSW Harvester, its capabilities URL must be URL-decoded.

Otherwise it is not possible to use the harvesting XML interface from client applications if these URLs contain characters such as & : if the client doesn't URL-encode them, GN chokes; and if they do, GN doesn't URL-decode them, and they don't work.

Probably this should be fixed in all types of harvesters for all inputs, but leaving that for when you need that.
