page load perfomance improvements...
remove the lists.js file from the <head>, which slows down page
load a lot (over 300K), and instead load it dynamically on page load.
also remove navtree_data.js from the <head>, which also slows the load
and is only used in the reference when in tree view. This file is now
loaded during the initialization of the nav tree.
