* 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).
* [xharness] Don't crash if we can't find a simulator.
* [xharness] Create a device pair if none applicable is found.
* [xharness] Use an enum instead of string values for the target.
* [xharness] Unify the simulator selection code between Jenkins and Wrench.
