feat: Add ability to automatically org-babel based on file category

[Randy1Burrell]

Using Emacs is a tool for productivity that performs functions with minimal effort. Therefore, I have added functionality that makes org-babel run in org-mode based on the file level property which the user chooses. This will help to give a productivity boost to the user.

If applied, this commit will:

• Run orb-babel automatically when the file level CATEGORY property is present and have a value of Configuration
• Fixes #38
