Display errors if the bundle cannot be loaded

[igmoweb]

This is a bit crazy idea but I created a script that will display an error in case the bundles are not found or cannot be loaded. I believe that falling back into production bundles if the dev ones aren't found is not a good idea as it could confuse developers. This will display an error with some details.

This makes some sense to me but I'd like to get input from @rmccue before we move forward.

Looks alright to me.

Where are the styles for this error taken from? Could we copy CRA's error styling instead? (You can use react-wp-ssr's exception handler and CSS as an easy way to grab that.)

@kadamwhite @rmccue I've updated the PR:

• It now handles the error from PHP, no external JS/CSS is needed to be loaded
• Execution stops when the error appears (this will prevent any other style/JS from the theme to be loaded that could change the aspect of the error).

Here's a sample:

IMO, if we're going to have monospaced text, we should keep the content plain text. I'd drop the ULs here in favour of just straight up text, or show the error differently.

@rmccue Thanks, should be solved now.
