add travis.yml, drone.io build helper

* add travis.yml, drone.io build helper ( droneio_build.sh )
* fix issue #6 
* added travis.org and drone.io badges (already configured for the user "mpasternak" in travis.org and drone.io)

On travis, the tests are passing with python 2.6 and 2.7 using Django 1.6.2
I left as an example configuration using Django 1.7 (it is still necessary to implement the apps.py file. see more: https://docs.djangoproject.com/en/dev/ref/applications/ ) and testing using python 3

see tests on travis: https://travis-ci.org/luzfcb/django-monitio
and on drone.io: https://drone.io/github.com/luzfcb/django-monitio
