v0.11.1

[ReenigneArcher]

Description

• Add CHANGELOG.md and update history
• Update .github files
  • create_package.yml (Responsible for PR build tests, Packaging, Automating Releases when push into master branch)
• Dockerfiles
  • Renamed Dockerfiles for ubuntu (required for matrix in create_package.yml)
  • Improved readability of build time requirements
  • Added Fedora 33 and 35 Dockerfiles
  • Added Ubuntu 18.04 Dockerfile (build is currently failing)
  • Use update-alternatives instead of cp for gcc on Ubuntu 20.04
  • Clean cache after apt-get update and install
• Add AppImage

Note: Once this is merged. The workflow should run and attempt to create a release. The release will fail because the latest version from the CHANGELOG.md matches the latest released version (v0.11.1); however getting this into master will setup the automation for all future PRs.

I know that everything in this PR has already been reviewed once when it was merged into nightly, but still figure it's best to have a review... even though none of this actually modifies the core program and is all pretty much repository items.

Like I said before I'm not a huge GitHub Actions user, but it seems okay to me (especially the Windows side which I'm more accustomed to), LGTM
