Support 'Open in Xcode' cloning button
Description
GitHub has support for cloning a repo and opening a project in Xcode from the home page of a project. Gitlab should do the same.
Proposal
To support an 'Open in Xcode' button just add button/link from the project's homepage with the scheme
xcode://clone?repo=<URL_encoded_repository>
