Provide a blank editor to test config.yml for lint errors
It will be nice to have a link in the UI that opens a blank config editor page where config can be pasted and used for linting and verifying.
This way users don't have to worry about editing existing projects if they just want to receive live feedback when editing config.yml files.
This should be relatively easy since the functionality already exists, it just needs to be provided without being tied to any Git projects somewhere in the UI.
Bonus: This functionality can probably be extended in the future to initialize and run VCS agnostic builds too!
