- Added GTMTestTimer.h for doing high fidelity timings.

 
- Added leaks checking to iPhone unit test script. It can be controlled by
  the GTM_DISABLE_LEAKS environment variable

- Added ability to control using zombies to iPhone unit test script. It can be
  controlled by the GTM_DISABLE_ZOMBIES environment variable

- Added ability to control termination to iPhone unit test script. It can be
  controlled by the GTM_DISABLE_TERMINATION environment variable

- Fixed several leaks found with leak checking enabled.

- Added configs for different iPhone OS versions.
