Fixed bug in 100% packet loss response. Errors from ping are now sent to irc.error(). Added packet count, interval, ttl, and wait options. Added additional test cases. Also, Enabled threading for Unix plugin, and for wtf, spell, and ping commands. Signed-off-by: Daniel Folkinshteyn <nanotube@users.sourceforge.net>
