Remove reliance on a system-provided python2

[YesThatAllen]

Immediate workaround:

Install python2 and edit the scripts' path

On an Intel mac, or Apple silicon with Rosetta2, it is possible to install python2 using Miniconda.

Example steps:

• Install Miniconda. Select the boot drive, not a user home, during installation.
• Disable the miniconda prompt (unless it is desired) conda config --set auto_activate_base false
• Install a copy of python2 eg conda create --name p27 python=2.7.15
• Edit the existing BackupMinder's script's shebang.
  • In: /Library/Application Support/BackupMinder/BackupMinder
  • Change the shebang to #!/opt/miniconda3/envs/p27/bin/python2

In this example, p27 could be anything. Validate the resulting path based on your system

Updating BackupMinder to Python3

There is an unknown amount of work to convert the following aspects:

• The script itself to python3
  

  backupminder/Library/Application Support/BackupMinder/BackupMinder

  Line 1 in 67a59b9

  #! /usr/bin/env python

• The BackupMinder GUI's project would need modernization.
• The BackupMinderHelper tool may need modernization.
• The project would need testing.

Further development of BackupMinder has not been planned, but resources are available for review of PRs.
