Use proxy for creating Gists

[juanghurtado]

Hi there!

I have changed the "send" method in gists.rb to check if HTTP_PROXY environment variable exists. If so, use it with Net::HTTP::Proxy.

It's the first time I write Ruby, so I'm sure it can be done better. Anyways, there you have it.

Thanks for your work!

Little improvement to the code, and use "http_proxy" instead of "HTTP_PROXY".

Thanks @antonio for this last change
