Closes #299

Procedure to create/update requirements.txt:

git clone https://github.com/pdfminer/pdfminer.six.git
# create a virtual environment
virtualenv vp && source vp/bin/activate`
# install the pdfminer.six package
python setup.py build install
# freeze requirements
pip freeze > requirements.txt

Actually, this should probably include a step that exercises more parts of the code, such as the PIL reference mentioned in #299.

Hi @charlesreid1,

Thanks for your PR!

Is there any particular reason that you included the versions of those packages? My personal preference is to to specify only the major version of the package.

Also, like you said, PIL is also a dependency of pdfminerl.six.

The setup.py should also be updated in this PR.

The .travis.yml should also be updated by this PR.

pdfminer.six is not a depencency of pdfminer.six ;)

@charlesreid1 what do you think of my additional remark:
