Copied in the masterchain.info source from mastercoin-tools (as of 6f6871bd00132b26c84e0762b2b7bed48fcb5f4c).
Changed www/server.py so that it serves bitcoin data out of /tmp/msct-wallet/www, and changed app.sh so that it spawns the server in the background.
Re-parse blockchain data periodically, and kill the web server process when the app.js is killed.
