vsend-and-flot

ENH: works with vsend murfi. // FIX: flot stabilized // BRK: rtmodal unstable
-- murfi xmls that are generated won't work with nonvsend murfi anymore!
-- flot namespace collisions reduced, json template formatting fixed, autoends fetching... 
-- BRK: modal sometimes fails to show up during a new rt session (not a flot issue).  starting a new incognito window seems to workaround the problem.
