* replace Clique with V6 in unit tests
* no hard mode in V6
* modify regex in copy_world to allow : str
* oops
* I see now
* work around all typing
* there actually needs to be something
* Test: add hosting simulation test
* WebHost: add weak typing to get_app()
* MultiServer: add typing to auto_saver_thread
* MultiServer: don't cancel task, properly end it
* customserver: stop auto-save thread from saving after shutdown
and make sure it stops, another potential memory leak
* MultiServer, customserver: make datapackage small again
* customserver: collect/finish room tasks
Hopefully fixes the memory leak we are seeing
* CI: test hosting
* Test: hosting: verify autohoster saves on Ctrl+C
* customserver: save when stopping via Ctrl+C
