Title: Add Keywords to Observable

@wick2o I wasn't able to push a new commit to your branch, so I copied it to a branch locally. I'm going to merge this, but it shows the standard way of adding a new field to a class in python-cybox. Hopefully it's useful if you want to add other fields in the future.
