Added jsTerm.

The entire jsTerm package is in the top level of the project.
Added jsTerm.js

The analogue to noVNC.js, where the magic should begin happening!
Added ssh_popout.html.

This is required for feature compatibility.
Added support for reaching new static jsTerm files.

The static files are now reachable via 'jsterm'.
Protective int casts!

They may not be requird, but they're in the other routine so I put them in this one.
Add separate tab for SSH and transform jsterm.html to use jsTerm!

The separate tab is temporary for testing purposes.
Updated class models, URLs and views to support SSH.

Tons of new methods, URLs, and such -- mostly cut and pasted from VNC.
