refreshing hit counts works with Chrome and node.js simultaneously
map local path /XXX/XXX/file.js to URL /file.js
Chrome sends scriptWentAway events as well
the log populates from both node.js and Chrome
kinda remove things from the log when their file goes away
fixed a bug: dead log items weren't being deleted
clear items from the log and log query when the connection goes away. close the log if no nodes are left.
sort log entries by timestamp
