Add a timeout when fetching a job from the persistence layers.
It's my intention to add more timeouts, so this also introduces some code
to make it easier to test that a context has a deadline set.
Deduplicate API implementation code to fetch a job from the persistence
service.
Almost no functional changes. Checking that the requested job UUID is
actually a valid UUID is now consistently done on all fetches. This is
not a functional change in normal Flamenco operations, where only valid
UUIDs are used anyway.
Expand the 'Variables' page so that it links to the two-way variables
page from within the body of text. Having the link in only the side-bar
was too easy to miss.
Move the "Custom Job Types" expandable section to its own, normal
section.
The expandable sections in the docs aren't that clear, visually. It's
easy to miss that they can be expanded. This was the only use of this
feature.
Add support for Blender's `use_all_linked_data_direct` experimental
option. This is a workaround for an issue with BAT, for which a quick
solution is required by the Blender Studio (production crunch).
Flamenco writes the `.flamenco.blend` file with
`preferences.experimental.use_all_linked_data_direct` set to `True`, so
that BAT has an easier time finding linked assets.
Run `PRAGMA journal_mode = WAL` and `PRAGMA synchronous = normal` when
connecting to the SQLite database. This enables the write-ahead-log journal
mode, which makes it safe to enable "normal" synchronisation (instead of
the default "full" synchronisation).
When a command (like `blender` or `ffmpeg`) outputs lines that are longer
than our buffer, they are broken into buffer-sized chunks. Extra code has
been added to ensure those chunks consist of valid UTF-8 characters.
The preview video task would attempt to use JPEG preview files when the
"Preview" checkbox is checked, even when this checkbox is not shown in
Blender's UI (when the output format is not EXR). Blender still stores
this property, even when it's unused, and that's what tripped up the job
compiler.
The "Simple Blender Render" job type now first checks whether the previews
are necessary at all, and only then uses them.
If file has never been saved, Flamenco cannot create a temp copy to
submit. This caused an exception, which is now avoided by showing a
clear error message instead.

Remove the "what is new" link, because it's not that relevant for a quick-
start page. Also it got lost a bit between the videos and felt out of
place.
Add an endpoint that mimicks the job submission endpoint, to see whether
the job survives the job compiler script. This can be used to fail early,
before actually sending files to the farm.
The two-way variable replacement function changes the submitted job. To
clarify that this happens, pass the pointer `&submittedJob`.
Both pass-by-pointer and pass-by-value work, because the variable
replacement typically works on maps/slices, which are passed by reference
anyway. Better to be explicit about this, though.
No functional changes.
Fix an issue where workers would switch immediately on a state change
request, even if it was of the "after task is finished" kind.
The "may I keep running" endpoint wasn't checking the lazyness flag, and
thus any state change, lazy or otherwise, would interrupt the worker's
current task.
Fix a BAT error that arises when submitting a job from a Windows
workstation to a Shaman flamenco system. BAT expects an absolute path,
but on Windows systems, absolute paths begin with a drive letter.
This patch adds an arbitrary drive letter, and later removes it once the
relative paths have been computed.
