Document installation & use of sqlc.
Installing sqlc is only necessary to regenerate the database code. Once
generated, the code is independent of sqlc.
GORM has certain downsides:
- Code-first approach, where queries have to be translated to the Go code
required to execute them.
- GORM comes with its own SQLite implementation, which doesn't provide an
on-connect callback. This means that new connections cannot correctly
enable foreign key constraints, causing database consistency issues.
[SQLC](https://sqlc.dev/) solves these issues for us.
This commit doesn't fully replace GORM with SQLC, but introduces it for
a few queries. Once all queries have been converted, GORM can be removed
completely.
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
