Password

@AmbientOSX 

I'm going to merge my changes into your branch. A lot of this is HTML/CSS id renaming. I made some changes to instrumentation code, fixed some bugs, etc. Also added the password field.

I can't test this locally, it seems. I think it has something to do with HTTPS. Getting `POST [url] net::ERR_INSECURE_RESPONSE`. Can this be resolved or will I need to test directly from the server?

I still need to fix a bug that is preventing backspace and delete from working in the password field.
