Another try.
Purge numpy from travis to force build from source
added pip freeze to see what's in the travis env
Fixed pop -> pip, uninstall numpy via pip
Uninstall all requirements from requirements.txt
Added more dependencies
all-deb -> all-dev
Added --verbose to see why build is failing for python 3.3
Added pip install numpy to before_install:
Moved requirements.txt to  before_install
Insstall numpy before requirements
Added --quiet to pip
Remove --quiet as travis will fail with no output for 10 minutes.
Added exit if unittest fails
Merge branch 'travis'
