Add Python wrapper for the HTML-based debugger (#1736)

The patch aims at easing the startup of the HTML-based JerryScript
debugger client by adding a python script that starts the default
browser with the HTML page implementing the debugger client.
Additionally, the pyton script encodes the host:port address
information of the debug server in the file url and the HTML client
is extended to retrieve this information. Thus, both the console
and the browser-based debugger client can be started similarly.
