Title: Show connect devtools button or allocated remote debugger port 

Change needed to help developers to connect the upcoming remote developer tools to debug or interact with remote webconsole on the running b2g instance:

- show connect button on Firefox >= 20.0a1 (where connect devtools xhtml page is available)
- show allocated remote debugger port on previous Firefox releases as fallback
