Implement dummy body message to indicate high priority push This adds a dummy body sent alongside the push when the original message also contained a body to indicate a high priority push. The body can be configured and its contents are generally meaningless with most app servers because it will be stripped before pushed to the client.

Description
===========

This module listens on presences containing caps (XEP-0115) and asks the client
for the corresponding disco#info if it changed.

It fires the c2s-capabilities-changed event once the disco#info result is
received.
