[HTTPS-Everywhere] https-everywhere bug with channels not attached to a window

[Loic J. Duros]

I've been writing a lot about my issue with xhr and Https Everywhere in 
extension code.

After struggling with XHR and the "request" module from the Add-on SDK, 
I'm happy to say that there's a solution just using a channel and 
asyncOpen instead. I've posted a short explanation and code sample of 
the solution in case someone else needs to perform xhr from their 
extension and never get a response when Https Everywhere is on:

Thanks much for all your support in helping me figuring this out,

Loic
