Fixed requirements handling:

Moved dependencies on packages into setup.py and added version pins in
requirements.txt files.

Also re-ordered the way travis installs:

First we install using requirements.txt (and thus get the desired
versions) then we install using `pip install -e .` which should not
install any new packages.

See:
https://packaging.python.org/discussions/install-requires-vs-requirements/
for current best practises regarding dependency handling.
