Title: Fixed subscription problem with new GNU Social.

I noticed that subscribing to StatusNet accounts on the new GNU Social code base did not work. The format of the .well-known/host-meta thingie has changed a little, and Friendica needs to explicitly accept only XML (otherwise it gets JSON). This patch fixed the problem (and still works with old StatusNet instances).
