Feature phpunit

1st: automatic phpunit test support via travis-ci.org for github
Needs some steps from you @picandocodigo :
phpunit testing via travis-ci.org

- just merge the request
- go to www.travis-ci.org and login with your github creds
- open https://travis-ci.org/profile (if you not get redirected there - you might be)
- activate the plugin
- DONE :smiling_imp:

2nd: better structured readme for github with indicator for build status

3rd: .git* files to prevent issues with cross-platform contribution and garbage by some applications and OSes
