At MT4.2rc1

Updated to MT 4.2rc1 and already there are a few templates that need modification so excuse any breakage you might encounter (drop me a line if you do find some breakage).

Still digesting all the new things (never really did get around to digesting all the template tag changes between 3.3x and 4.1) and I still need to get around to mucking around with my templates so things build a little faster. From the looks of things, there are a lot of new things. MT's templating system is has almost become a full-blown programming language in itself!
