chore(CI): configure Travis and Codecov (#324)

* Create .travis.yml

* Update .travis.yml

* Update .travis.yml

* Update .travis.yml

* Calling nvm in 'before_install'

* using string instead of 'class' property for php 5.4

* Utilizing customary method for accessing json_last_error_msg, in case it doesn't exist (php 5.4)

* Forced installation of 'process-nextick-args' for travis

* Additional comments + force travis to rebuild

* Local install only

* Added missing 'isarray' module

* Shifted travis related dependencies into package.json

* Added 'buffer-shims' module

* Testing with new parse-server-test

* Updated package.json, added slight delay after server boot

* Adds coverage report

* Update README.md
