Get notified about every Hacker News submission (OSX)

not before I clean up the code a bit - just hacked that together, and variable names are still in Polish :)

it's really basic anyway: html parser + NSUserNotification + NSSpeechSynthesizer, I think it's 5 mins to replicate for anyone acquainted with XCode (I'm not using it on a daily basis, so it took an hour or so)
