Close issue 41, remove obsolete gtk 1.x code, trap os.getcwd exceptions at init time.

Simple change to add svn revision info at the top level and crash handler. Useful for debugging.

Added .complete() method to ipython. This exposes the attribute completion machinery which normally only readline sees. It will be useful to Brian for the remote kernels, and also for the GUIs to do tab completion. Please merge into chainsaw/tzanko branches.

Testing post-commit hooks...

Trivial test for svn post-commit hooks

Update version strings to use only dots as separators, since either - or _ will break one of bdist_rpm or bdist_deb, so we must avoid both.

Fix incorrect link in OSX instructions.

Close http://www.scipy.net/roundup/ipython/issue40, add OSX install info to manual.

* IPython/iplib.py (runsource): remove self.code_to_run_src attribute. I realized this is nothing more than '\n'.join(self.buffer), and having the same data in two different places is just asking for synchronization bugs. This may impact people who have custom exception handlers, so I need to warn ipython-dev about it (F. Mantegazza may use them). * Fix http://www.scipy.net/roundup/ipython/issue38

Minor improvements, to add changeset info.
