Change all null checking expressions to use 'is null' and 'is not null'
instead of '== null' and '!= null'.
This was mostly done with sed, so code can probably be improved in many
other ways with manual inspection, but that will come over time.
Also add code to the autoformat script to automatically fix these issues in the future.
* Add a server mode, which launches a web server (and a web page) that can be
used to interactively run tests and view their results.
* Add support for running test assemblies in a today extension (generating a
new set of projects, similar to how we generate tvOS/watchOS projects based
on the iOS project, we now generate a today extension project in addition to
the tvOS and watchOS projects).
* Load all the different tests (and show them in the html report, although
they show up as 'ignored'), even for disabled/ignored tests. This makes
disabled/ignored tests more visible, and also makes it possible to actually
run them using the embedded web server.
* Add support for running tests on device. Tests will be executed on multiple
devices simulatenously (any connected devices will be used).
