PythonOption action-path is required but undocumented

[Forest]

The README says:

"When you're using this default configuration, the location of the login screen will default to '+login' within the root of the directory that you put the PythonAccessHandler directive."

This appears to be out of date. By default, it uses the hlist.location member of a mod_python Request object to determine the path for actions like '+login'. Unfortunately, htlist.location is always None on my Ubuntu Lucid system. In fact, Request.hlist isn't even a documented part of mod_python. The result: apache-openid raises an unhandled exception (AttributeError: 'NoneType' object has no attribute 'endswith') and triggers an apache internal server error.

So apache-openid's actual default behavior is to not work at all.

Some investigation revealed that setting an action-path PythonOption can work around the problem. As far as I can tell, this is not documented.
