[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.
I'm a little concerned we are taking an existing flag that referred to milliseconds and replacing it with a timeout that refers to seconds. Why not keep it at milliseconds?
