update setup.py classifiers and MANIFEST.in
remove builtins reference from setup.py (what was it used for?)
add .travis.yml file for testing on travis-ci.org

scipy version in the travis apt-get repo is too old for AlgoPy: using recent version via pip now
copied before_install from scipy's .travis.yml to install the scipy compile dependencies
Using ppa:pylab/stable to download scipy on travis ci

add sudo apt-get update
Release 0.5.0
change bibtex of algopy paperl, article is now also available in printed form
fix two typos in comments
