WIP: Very much a work in progress.
- We now have a custom task factory and task scheduler. They're both still very ugly but they're a whole lot more solid under thread-starvation conditions.
- We also have a new StressTests assembly where we can add stuff that hammers at the bus for longer periods.
- First cut of property injection for handlers and interceptors (needed for event/command/event/command/event cascades so that handlers can publish stuff to the bus in our test harnesses).
- Wired in Serilog for stress tests
- Started using Serilog-style log message formatting wherever I've touched code. We normalize this down to a string.Format(...) template where we need to so standard loggers won't break.
