development already. The "Get Involved" page now links with a CTA button
to the "Development" page.
The flamenco.io website moves to flamenco.blender.org!
This commit updates the Makefile as follows:
- Rename 'site' to 'project-website', so the new command to deploy is
'make project-website'
- Move the website directory from 'flamenco-io-site' to
'project-website'
- Update the rsync command do reflect the new deployment destination
