[TIMOB_17601] Added ioslib 0.2.9 which fixes handling of launch timeouts...

... and added extra debugging output. The default launch timeout is now 3 minutes which should be large enough for users launching an iOS 8 simulator on a really old, slow Mac. Added 'ios.simTimeout' config option to override the 3 minute default.
It's a new flag as far as I'm concerned. This PR removes the timeout from JS (milliseconds) and uses ios-sim's built-in timeout (seconds) which is way more reliable. ios-sim passes the timeout directly into the simulator private APIs, which is in seconds, not milliseconds. Oh well.
