Install & Start scripts for the web server

Added configs so that msc-webwallet can be cloned, and then "npm install" will check out the latest version of mastercoin-tools.

Copied the web server portion of mastercoin-tools into this repo, so we can begin reworking it.

Added a start script which will create a working space in /tmp/msc-mastercoin, launch the python based server, and then start parsing & validating the blockchain into that space.  Transactions and other resulting JSON is served directly from the /tmp space (this should be moved to someplace else that's guaranteed to be writeable, I think).
