Catch all of Spiel's initialization errors
Re-locate the initialization of Spiel so that all errors are being caught, and Orca isn't left in a broken state. In the rare case we're passed an invalid argument, catch that too.
Also update the README to use meson devenv
for a more reliable
development and testing environment. This should avoid troubleshooting
any problems caused by manual setup.
