Add lint.Fprint helper for unchecked fmt.Fprint calls.
Use lint.Fprintf/Fprint in api/event.go, api/image.go, rmo/root.go.
Add explicit error check for fmt.Fprintf in middleware/terminal.go cW.
This is a pretty big refactor of how communication works to start moving
us in the direction we want to go long-term. This adds the new
communication row and migrates existing reports to add rows for
communication.
There's also a bunch of automatic fixes from the new linter. I should
have added them separately, but whatever.
This involved moving a lot of stuff to the platform layer since I don't
want event interfaces leaking out.
Also this includes a fix to the user authentication which I had
previously broken by making a platform-layer user object independent of
the database layer.
The goal of this rework is to make it so I can pass around platform.User
instead of a pair of models.Organization and models.User. This is useful
for reason I kind of forget now, but it started with working on
notifications and ballooned massively from there into refactoring a
number of things that were bugging me.
This also includes a tiny amount of work on server-side events (SSE).
* background stuff lives inside the platform now, which I need for
having it push updates through SSE
* userfile now lives in the platform, under file, so other platform
functions can safely use it
* oauth is broken into pieces and inside platform because other stuff
was calling it already, but badly.
* notifications go into the platform as well
