Update .travis.yml

[junaruga]

I updated Rubies to latest version. I also added ruby-head as allow_failures.

I think this is useful. Because we can support the next version Ruby as faster.

We can see this kind of logic in rails, rspec and cucumber and etc. https://github.com/rails/rails/blob/master/.travis.yml https://github.com/rspec/rspec-core/blob/master/.travis.yml https://github.com/cucumber/cucumber-ruby/blob/master/.travis.yml

Is it possible to merge?

Thanks.

Only Ruby 2.2.7 test was failed. Is this a known or temporary issue?

 1) Error:

I tried again, and I got same error for Ruby 2.2.7 and 2.4.1. It looks the issues that sometimes happens. https://travis-ci.org/jonleighton/spring-watcher-listen/builds/225307729

@jonleighton Finally I passed all the tests.

I did below things to prevent the error Errno::EBADF: Bad file descriptor that are sometimes happened. I thought the solution was saving the resource to build.

• I stopped unit and acceptance test in parallel from I updated Rakefile to run unit and acceptance test sequentially. (Maybe the most important factor)
• cache: bundler to save resource to build.
• Use newer Ubuntu OS version Trusty than default OS version Precise for reliability
• sudo false to prevent full VM per build.
• Use latest stable version of Rails 5 for reliability.

I was inspired from rails/spring for the .travis.yml and Rakefile. https://github.com/rails/spring/blob/master/.travis.yml https://github.com/rails/spring/blob/master/Rakefile

Could you check and merge it? Thanks.

The result of task list is like this.

$ bundle exec rake -T
rake build            # Build spring-watcher-listen-2.0.1.gem into the pkg directory
rake clean            # Remove any temporary products
rake clobber          # Remove any generated files
rake install          # Build and install spring-watcher-listen-2.0.1.gem into system gems
rake install:local    # Build and install spring-watcher-listen-2.0.1.gem into system gem...
rake release[remote]  # Create tag v2.0.1 and build and push spring-watcher-listen-2.0.1....
rake test             # Run tests
rake test:acceptance  # Run tests for acceptance
