Included in the changes: - create a new /api root package to hold all API code, migrate /graphql in there - git API handlers all use the cache instead of the repo directly - git API handlers are now tested - git API handlers now require a "repo" mux parameter - lots of untangling of API/handlers/middleware - less code in commands/webui.go
