* Restricted Linux CI build to only run on changes to code,
translations, software lists, and build scripts.
* Restricted Windows/macOS CO to only run on changes to code and build
scripts. They provide nothing over Linux for the other stuff.
* Added plugin properties and controller file validation to the "hash"
workflow.
* Added a workflow for building documentation, so pull requests that
affect documentation will at least get a basic check in advance.
-plugins/autofire: Bumped version as configuration format has changed.
* Create GitHub Action to validate hash XML files
This GitHub Action will run on any commit or pull request that changes a file in the "hash" directory. It will do a simple xmllint run for the HSI files and will check the softwarelist XML files against their DTD.
* Delete c64_flop_clcracked.xml
No content, can be recreated if needed.
* Remove references to removed softwarelist c64_flop_clcracked.xml
