Update gotak import path to fix Travis build
Update import path in the gotak subdir so that Travis tests can be played
against the Github repository.
Also, add missing dependencies to the Travis YAML file.

[![Build Status](https://travis-ci.org/McKael/takuzu.svg?branch=master)](https://travis-ci.org/McKael/takuzu)
This repository contains a [Go](https://golang.org/) library package that
provides functions to solve, build or validate takuzu puzzles.
- Mercurial repository: https://hg.lilotux.net/golang/mikael/takuzu/
- Github mirror: https://github.com/McKael/takuzu/
Please read the [godoc documentation](https://godoc.org/github.com/McKael/takuzu) for details.
# CLI demo
This project also contains a command line utility, named `gotak`, to solve or
generate puzzles.
I haven't written the tool documentation yet.
To build the gotak CLI utility, you can use
```
go get github.com/takuzu/gotak
```
(If you use the Mercurial repository, you have to update the import path manually.)
# Online puzzle demo
This library is used by GotakJS, an [online takuzu puzzle game](https://lilotux.net/~mikael/takuzu/),
written in Go using [GopehJS](https://github.com/gopherjs/gopherjs).
(On mobile, works best with Chrome. On a computer, I've tested it with both Firefox and Chrome.)
