Added travis.yml build file

[mieciu]

Travis.yml config with many Ruby versions added for CI

Thanks, @mieciu! Could you clarify how you're using CI for this repo, or maybe why you're stuck building it? Trying to figure out how this fits in.

Hi @troy ,
First I saw this issue: #42, and thought I might somehow help with it.

You can have a look on this travis builds here:
https://travis-ci.org/mieciu/papertrail-cli

Basically it checkouts the project, and (for various versions of Ruby) runs bundle install and also executes just the default rake task with bundle exec rake.
I guess this project need more tests, scenarios, and everything, but I believe that linking it to Travis is a beginning 😄

Yeah, I know Travis well, I just didn't understand why someone would add Travis but not any tests :) Are you using Papertrail and using this gem?

[troy]

And thanks for caring enough to help, too! :)
