General lab improvements

Ideas for lab improvements so that it is nicer to use:


 * Raceways along the walls for ethernet plugs
 * Overhead power drop- this will cost $$ to do it ourselves (~400ish?) and $$$ to have Caltech electrical do it (~$1500+). It would be very nice though
 * LCD monitors
 * Make the AC quieter
 * Fix the stereo
 * Get more track lighting
 * Get lednet working
 * Replace the tables
 * Microwave
 * Vending machines
