Changed everything to only look at a single set of environment variables, making reTOracle more friendly to use with uWSGI server.
Added run_local.py, which can be used to run rheTOracle.py locally using uWSGI and not Flask development server.
Updated requirements.txt with uWSGI packages.
Lots of changes. run_local.py can be used to run rheTOracle.py on local clients using uWSGI. All other .py files now use environment variables exclusively. Still not putting application logging to stdout along with uWSGI output yet.
