Wt

There are a few Wt tests that take a long time (tests with sleeps in them, database benchmark tests). I don't think we should run them as often as the other tests, since they're just holding up our CI builds.

I propose we split them off into separate executables, only to be run on the builds that are run less frequently, like only once every day.

Alternatively, we can add some CMake option that disables the slow tests.
