dotCooCoo 099b89f53d Preflight: check the document on a background worker, not on every edit ...

The status bar's error count ran the whole-document preflight check on
the interface thread for every new state of the document, so every drag
step and every typed character waited for it. The Preflight panel ran
the same check on every frame. The check composes every story and asks
the file system about every linked graphic, so its cost grows with the
document: on a 300-page document with 900 placed images it took 137 ms
on a fast machine, and moving or resizing a frame and typing became
unusable on large documents.

The check now runs on a worker thread that takes the newest state of
the document; the issues last found stay shown until it answers. An
unchanged document is checked again every few seconds for linked files
changed outside the app, a save under a new path or a font reload is
checked again, and a check blocked on another document's linked file
is handed off to a fresh worker after 200 ms. Tests and the web build
check on the interface thread, once per state of the document.

preflight::check_document takes the document, the composition cache and
the save path, so the worker needs no session.
