Current version `0.8.1-snapshot` is not valid according to PEP 440 and causes installation problems

[johann-petrak]

Not sure why I did not see this before but when I try to do something like pip install -e . from a freshly cloned version, I get these error messages:

  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error

[minuenergy]

same problem. did you fix this??

[johann-petrak]

This specific problem is easy to fix locally, just edit ./farm/_version.py and replace "0.8.1-snapshot" with something that conforms to the Python version number scheme, e.g. "0.8.1.dev1"

However there other problems of this repo due to bit-rot and missing maintenance, e.g. with which package version the installation process wants to pull. To get it to run you may also need to update requirements.txt before doing the installation.
