From e19b5124101f2ff5aa755df99b0fcbd0923aa01f Mon Sep 17 00:00:00 2001
From: Christopher Lenz <cmlenz@apache.org>
Date: Fri, 9 Jan 2009 18:20:37 +0000
Subject: Refactoring in Futon to clean up interactions between specific pages
 and the navigation. Also, switched some graphics over to PNGs with
 alpha-transparency (screw you IE6), and added a button for removing databases
 from the recent databases list.
