Raise our IRC connection timeouts

ZNC will now send a PING if the connection was idle for 270 to 300 seconds.
After 540 seconds (that is, about 270 to 240 seconds later) the timeout is
triggered and ZNC reconnects.

These values are "inspired" by the values eggdrop uses.

The old timeouts were 180 to 210 secs for the PING and 240 secs for the timeout.
