Spice html

Add the long-waited spice-html5 support to foreman.
Now it is possible to connect to a console of a vm that runs with spice console from any
modern browser no need for a spice xpi installed.

To use the Spice XPI (better performance and end-to-end encription) use Firefox on a Linux machine install the XPI (yum install spice-client) and press the "new window" button on the console page.
