`lib/controller` now ignore test files. Not ignoring test files would means that
the runner would try to load them into the client resulting in errors.

Update tests to check this behavior.

Fixes #12.

client config is now set globally via config file

Closes #10

See merge request !10

Client config is now defined in `config.json` and injected by the runner into
the client side.
This allows to pass a single unified config object to each client-side script.

Refactor previous system into this.

Closes #7

We now use the function defined in `lib/controller` to load the resources to
inject into the client.

The order of the "modules" to be loaded is defined as follow:
- controller
- lib
- robot

Each module corresponds to a specific folder in the `client` folder.

This module allow to load all the files that must be injected into the client.

We define three modules to be injected in the client:
- controller: in charge of exposing the hubl.in functions as a unified API
- lib: containing various libraries to be used by the robot
- robot: containing the behavior of the robot itself

Currently these modules only contain the base skeleton.

Instead of a single controller file, `runner.run` now takes a list of source
files that will be injected in the passed order.

- `robotClientController.js` moved to `client/controller/controller.js`
- `controller` renamed to `robotController`
- changed some `var` to `const`
- updated path to controller in `app.js`

Update package.json

See merge request !1

`package.json` contained a lot of missing or incorrect info. Fixes this.
