add travis-ci integration and automatic django testing

the testing is done with ```django-setuptest``` that help to setup up stub Django environment in order to enable stand-alone app testing.   
for this to work in the main repo, you should allow this repo on travis-ci.(after logining in as Django)
and also change in the Readme.rst the image link to the django/django-localfflavor-il
only need to change the travis-ci png 

for some reason this pull requests also includes the files changed in the previous pull requests. I guess you can fix that
