        libpurple/protocols/jabber/jabber.h

ChangeLog: 

Support pushed notifications about XEP-0191 Blocks/Unblocks. Closes #8045.

Recompiling jabberd2 from scratch magically made the pushes work, so I was
able to test this and it works, except for causing a crash in jabberd2 that
Mark already fixed. :)
