Merge in Skip's last few updates w.r.t. py-help-at-point:

(py-mode-map): Bind py-help-at-point to f1 as well as C-c C-h

(py-help-at-point): Make sure the symbol is quoted so things like
pydoc.help('sys.platform') work correctly.  Also, leave the *Python
Output* buffer in help-mode; this may be a bit more controversial.
