more explicit node dependency

[jedireza]

It wasn't obvious that I need to have a node to run the selenium tests. This PR adds a package.json file so we can have a proper place for dev dependencies as well as defining the version of node that is supported (via the engines key).

Now locally we can simply setup via:

$ npm install

And then run the tests by having the Rust server running on port 3000 and:

$ npm test

If this is ok with you I'd like to add some instructions about this to the readme before merging.

About adding package.json - if that's ok with @fabricedesre then I also fully support that change - I kept it out because nodejs is only used for running the GUI tests right now.

About setting the hostname back to localhost - right now, there is no build process that sets the foxbox.local hostname, but I would like this to exist in the future, that's why I kinda like it being there in the GUI tests and in the user manual.

I'm fine with adding package.json too.

About the foxbox.local name setting, it should be set by the daemon itself to reflect the --name command line argument. We'll need the avahi bindings that @azasypkin is working on and implement something similar to http://www.avahi.org/wiki/Examples/PythonPublishAlias (without dbus).

I updated the README in #37 since I changed more than just adding details for Node. We should merge this first and that second.

I'm not a fan of the added complexity of needing to edit my /ect/hosts just to run tests locally, especially when I have the server (http://localhost:3000/) running already.

This PR adds a package.json

👍

I agree. What do you all think of:

• using localhost as the default hostname for selenium tests
• and create a separate test called FoxBox should be accessible by the domain name called "foxbox.local" (given by avahi daemon) ?

Then, if such a test failed on one's computer, the failure would document the intent.
