Run test, build and lint checks on Travis CI

This change makes it possible to run tests, integration tests and lint
on Travis CI. It also prepares a special Gulp task to perform the same
activities locally. This is handy when, e.g., sending a pull requrest.

Create API handlers infrastrucutre

This simple setup will be used for handling calls to the API, once
implemented.

Function that creates k8s apiserver client

It is a little bit overengineered. But I wanted to have go tests for
something. So I made it accept an interface.

Gulp tasks for backend unit tests

Fix unit tests and prevent protractor from hanging

Next change will actually implement some tests for the backend.

Once unit and integration tests are hooked to travis, such errors should
not happen again.

Add Go dependencies for kubernetes api client

This is what gets checked in when you do `go get
k8s.io/kubernetes/pkg/client/unversioned` and then save it.

Add service list and zero state views

This change is mostly boilerplate for the two views and cleanup of test
code that has been laying around.

Use Godeps dependency management for the backend

The Godep tool is de facto standard in the Go and Kubernetes
communities. So, the ealier this project switches to it, the better. The
setup uses recommended layout from the project docs:
https://github.com/tools/godep

You might wonder why to pull entire Godeps folder here. This is how
Godeps strongly advise to do.

Spawn backend application process on serve task

This setup autoreloads backend process on source change and ensures that
there is only one process running.

Follow up would be to wire this setup with browser sync to proxy API
calls to the backend.

chore(build): cache bower dir & rm global node packages

- Caches the installed Bower dependencies for faster builds.
- Removes global Node.JS modules gulp and bower from travis conf & make
	them devDependencies for more reproducable and faster builds.

Add browser favicon to the frontend application

Integrate build system tasks to make them work

This is build integration commit after my recent set of separate changes with standalone tasks. Now, every task works and produces reliable output.

Add new rules to ESlint checker and update code

Change Travis link from 'console' to 'dashboard'

Display travis status in the README file

Use webpack instead of jscompiler in dev builds

Webpack is much faster and does not do extensive file processing. This
means that when there is a syntax error, webpack often works correctly.

One downside is that I had to disable ng-strict-di. Will work on this
later to reenable it.

Kubernetes themed chrome with simple navigation

This is a chrome that has Kubernetes-like color palette.

This is to have unified codebase from the beginning of the project.

Rename Kubernetes Console to Kubernetes Dashboard
