Enables the Python tests to run with 2.3 (necessary for testing on Mac OS X Tiger); also fixes gtest_output_test when built with xcode.

Removing a warning when building from the command line. Reordering targets to be semi-alphabetical and to match the ordering in the Makefile. Cleaning up target names to remove the underscore (on the python-based ones), and adding 'run_' Xcode executables to run the python script from within Xcode. Whew
