package: update "proxy-agent" to v1
index: use `debug` component
index: fix the redirect http -> https scenario

Doing a kinda crazy hack of "watching" the `url` field of the
superagent Request instance, and when it's changed, then re-running
the proxy agent logic on the instance so that it can get a new Agent instance
index: fix redirects for the static proxy() fn call as well

Don't assume that the `proxy()` function is present on the Request instance
gitignore: ignore development files
v0.3.0
