Changes with Python Mode 3.105

• Improvements to the way the JPython or CPython shell is selected. There is a new variable py-default-interpreter which determines the default shell to use for py-shell (C-c !). The shell is now determined the first time py-shell is invoked or a Python buffer is visited.

  py-shell now also takes an optional argument; when given it will prompt for additional switch to pass into the shell process (only on initial start up).

  py-toggle-shells now takes the symbols cpython and jpython as arguments, making it more usefully called from python-mode-hook.

• New command py-narrow-to-defun (C-x n d) which mimics the standard narrow-to-defun but understands Python classes and methods. With C-u, narrows to the most enclosing class.

• Removed special bindings for C-j to py-newline-and-indent. This makes Emacs diehards happier, but may break for people who explicitly bind or C-j to newline globally.

• The usual assortment of bugs fixes, and some performance improvements (for FSF Emacs).
