rewrite in co generators

[jonathanong]

rewritten with the following changes:

• use cogent instead of super agent. we can switch back to super agent if it gets fixed.
  • handles gzip
  • handles redirects
• use graceful-fs over fs
• remove auth stuff (re-add after everything else works)
• remove proxy stuff (re-add after everything else works)

to do:

• readd auth stuff - i need tests
• readd proxy stuff - i need tests
• reimplement old api - changed it a little, but there's no need for that. we can change it later.

right now it works, but there are a lot of tests to be had. it's already much cleaner.

I'm down in concept, but please don't remove already working features. I spent a good amount of time making proxy and auth support consistent in this module.

[jonathanong]

@TooTallNate i don't plan to ever merge it without readding auth and proxy support, but i do need tests to make sure it's working correctly.

[TooTallNate]

@jonathanong Sounds good, just checking :)

[jonathanong]

@TooTallNate please add tests :) also, auth/proxy support in cogent or fixing super agent in general would be nice too.

[jonathanong]

@TooTallNate looking at your proxy stuff, it seems that all that's needed is options.auth = proxyAgent(uri, secure). is it that simple? also, i want to replicate your tests, but i don't know what's going on here: https://github.com/TooTallNate/superagent-proxy/blob/master/test/test.js#L56

[TooTallNate]

@jonathanong I think you mean options.agent = proxyAgent(uri, secure). The proxy variable in the superagent-proxy tests are just the URI to the proxy server. I made it configurable in the tests in case I wanted to use a different proxy server for the tests.

We can also take a look at proxy to spawn a HTTP/HTTPS proxy server up for the tests (a little bit of confirmation bias when using this module... but better then relying on external proxy services IMO).

[jonathanong]

cool. much easier than i thought. shouldn't be difficult. i was confused because it seems like you tested using a local proxy, but you don't have any comments or references on how i could create a local proxy as well. an proxy included with the tests (maybe even optional like how you're doing it right now) using proxy would be helpful.
