Fix requirements file.

[MichaelCurrin]

Figure out why this line is at the top "-f /usr/share/pip-wheels", in PythonAnywhere.

Errors on installing:

Collecting SQLObject==3.3.0 (from -r requirements.txt (line 12))
  Url '/usr/share/pip-wheels' is ignored. It is either a non-existing path or lacks a specific scheme.
  Downloading SQLObject-3.3.0-py2.py3-none-any.whl (1.9MB)
    100% |████████████████████████████████| 1.9MB 191kB/s 

That is repeated on each line of collecting.

Then create new virtualenv in my local repo.
