Update CI and switch to documentation tables based on xcore

- CI runs on push/pull_request to branches as defined in #435
- Generation of documentation tables is now based on xcore
- Documentation tables are generated for all those branches and uploaded to according subdirectories in GitHub pages
- Documentation tables are no longer stored in the repository itself
