SSL and livenet config by default

- set LIVENET and SSL config by default
- fix some minor issues handle the schema in the URL

Didn't add new tests since the current tests applies to the small refactor that was made on Insight.js `options` parameter to `_request`.
It's going to be a little annoying to test for development if we default to livenet. What happened to the config.default.js? The point of that file was so that you could keep your own local config.js file that was .gitignored and so you wouldn't constantly be bothered with whether you wanted to commit your local config to the repo.
