Feature request: using proxy

[GoogleCodeExporter]

Hi,

As I’m behind a proxy, I cannot directly use the current version (r148) of 
your wonderful bot.
So I added a “private Proxy proxy = Proxy.NO_PROXY;” field with a setter, 
and replaced the 5 “openConnection()” occurrences by 
“openConnection(proxy)”.
I could have extend the class, but copying and pasting the 5 impacted methods 
which can later evolve is not sustainable.

Thanks!
