Must-have
---------
- Check required fields before enabling Publish button
Should-have
-----------
- Save / load publisher messages (either as templates or to disk)
- Tapeti: export received messages to Tapeti.Cmd JSON file / Tapeti.Cmd command-line
- Tapeti: import Tapeti.Cmd JSON file into Subscriber-esque tab for easier browsing
- Tapeti: fetch NuGet dependencies to improve the chances of succesfully loading the assembly, instead of the current "extraAssembliesPaths" workaround
