Match install_requires conditions to less strict versioning in requirements.txt; bump version number

This commit matches the setup.py install requirements to the requirements.txt file; see commit https://github.com/rtkjbillo/hipsaint/commit/2ce3aaf7c578cfdf32829fad7f13aaba36e9825d for the original change. This change was necessary to get hipsaint working when we had newer versions of both the requests and Jinja2 libraries installed.
