Corrected behaviour of raw_input under windows. Recursive wx.yield is not that supported... So removed it and do simple modal call in non threaded mode.

skipping windows specific tests of get_home_dir on other platforms

Added a sleep as suggested by gael, so will not eat all cpu on raw_input request...

cleaner way to handle raw_input, done with a TextEntryDialog + __builtin__ overload as suggested by Ville. Works also with thread option

some more little cleanup and a bug correction with prompt that comes with last commit

Code refactoring to be pep8 complaint with functions names.

Fixing numerous bugs in ipcluster on Win32. * External processes are now started by calling "python.exe -u" * We find external process locations by importing them and using their __file__ attribute. This make the search robust against different ways of installing the scripts on Win32. * We now check to make sure that if the user wants to run in secure mode that pyOpenSSL is actually installed and working. This is now done in the controller, engine and ipcluster.

Fixing command finding bug on Win32 in ipcluster.py

Fix: output prompt is now displayed correclty.

Test for presence before deleting keys from os.environ. Mark two tests for skipping when not on win32 platform.
