We lacked a test suite that even just tried connecting to a server and
bouncing a few stanzas back and forth. The "runtests" suite does just
that. It connects to 2 accounts on a server (set in a config
file ~/.pontarius-xmpp-tests/pontarius-xmpp-tests.conf) and tries
passing some messages and IQ stanzas back and forth. This should clear
the way for more interesting scenarios.
move xpStanzaErrorCondition into the body of xpErrorCondition because it
is meaningless by itself and rename xpErrorCondition to xpStanzaErrorCondition
