icedove: clicking links does not spawn web browser

An old and easy to fix bug:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=425790

Add this:

pref("network.protocol-handler.app.http","x-www-browser");
pref("network.protocol-handler.app.https","x-www-browser");

to the /etc/icedove/pref/icedove.js file or to user.js in your user profile directory.
