New Nav release with friendlier window resizing

[Issac Trotts]

Hi Nav users,

A new version is up at http://emacs-nav.googlecode.com/files/emacs-nav-20110121.tar.gz, with the following changes:

* Nav automatically resizes itself after opening a file in another window.

* The window width can be fine-tuned using the plus and minus keys.

* The current width can be saved for future sessions using shift-w.

Enjoy,

Issac
