KV 4eedd94164 Add actions to compare against and restore from the latest commit
Add new actions:
- 'compare' action to compare generated files (except those
  generated by Graphviz) against the latest commit, and
- 'restore' action to restore generated files from the latest commit.

This is a squash rebase of these commits:
- p 9ad3e13 Reduce code duplication by moving common code into a generic function
- s d4feae6 Add action to restore generated files from git repository
- s 64f6507 Add action to compare generated files against git repository
- s 099c202 Simplify code
