Fixes #288.
This PR adds a global error boundary to catch errors that might occur during rendering of your app and display a pretty information about it:
I also discovered an issue when there would be "unhandled promise rejection" errors thrown when there's an error inside of a component. It was caused by
waitUntilExit()function and specifically,exitPromiseproperty in Ink instance. When Ink app is unmountedexitPromiseis resolved or rejected, which causeswaitUntilExit()to resolve. When there's an error and code didn't callwaitUntilExit(), no one is basically listening to that promise, hence the "unhandled promise rejection" error. I fixed it by creatingexitPromiseonly whenwaitUntilExit()is called.
