Revert "Test bumping the version (for gitlab-ci deployment testing)"

This reverts commit ac6e07f7.

Adding new Deploy and Publish steps to GitLab CI (simplifying releases)

Refactor due to profiling improvements (in libopenshot)

Adding more validations during the publish step, to verify openshot.org/download has correct URLs, which include the new version, and that all URLs are valid (no 404s).

Adding new deploy and publish scripts for GitLab CI to manually support deploying files/installers, creating GitHub release objects, creating blog entries, and creating new versions on the website.

Reducing size of AppImage (removing unused and duplicate files during freeze)
