Message 189339 - Python tracker

New patch: I renamed Itest to idle_test everywhere and re-ran tests; removed try-except from test_pathbrowser.py; and renamed @template to @README and rewrote. It applies cleanly to 3.4 on my system. The only problem applying to 2.7 is CallTips.py, which has different test code at the end. That will be easily fixed.
