make it work with browserify

The main issue preventing browserify usage was computed paths
in require statements: `require("./" + someVariable)`. Those have
all been eliminated.

This patch only adds browser support for `v3.0.0` (see the throwing
code in `/index.js` where it states exactly that to understand why).
Hint: it's related to computed paths again.

There were also a number of issues in `browserify-http`, and
`browserify-https` that I needed to code around to get things working:

  - browserify/http-browserify#90
  - browserify/http-browserify#21
  - browserify/http-browserify#10
