Issue #3: Adding CD from Travis to NPM

This commit updates travis to properly make a new release upon a new
version of the applicaiton. Following the documentation at
http://docs.travis-ci.com/user/deployment/npm/, I did all the changes.

I first installed travis from Ruby Gems.

$ sudo gem install travis -v 1.8.0 --no-rdoc --no-ri -V

mdesales@ubuntu [07/18/2015 0:52:58] ~/dev/github/node-pom-parser
(master *) $ cat ~/.npmrc
//registry.npmjs.org/:_authToken=52****-****-***-***-*****cd9

mdesales@ubuntu [07/18/2015 0:53:19] ~/dev/github/node-pom-parser
(master *) $ travis encrypt --add deploy.api_key
Detected repository as marcellodesales/node-pom-parser, is this correct?
|yes| yes

52****-****-***-***-*****cd9

From this, it completely updated the api value in the file
automatically. The only additional part added was about which branch it
should release from.
