Fix the issue

Version:           Git (using KDE 4.4.3) 
OS:                Linux

Currently a PING request is scheduled for each PONG received. When receiving
some unrequested PONG, too many PING are sent causing server flood. This occur
when using an irc proxy with multiple clients connected, number of PING
requests grows exponentially.

A simple check can be added to konversation code to avoid scheduling multiple
PING by ignoring PONG when no PING were sent. See attached patch.


Reproducible: Always

Steps to Reproduce:
Connect two konversation clients to a znc irc proxy on freenode. and you end up
being disconnected for flood in a few minutes.

Actual Results:  
You end up being disconnected for flood in a few minutes.
