Consider disabling script/style concatenation

[dd32]

Occasionally in Safari I get a unstyled admin page, seemingly because the wp-admin/load-styles.php call failed or timed out.

If static files are simpler for it to serve, it would be beneficial to remove the concatenation, as it serves no purpose other than to reduce network round time trips and most admin pages will have a different set of styles/scripts causing the browser caches to be ignored.

This can be done by using the following, which disables concatenation and gzip'ing of static resources.

define( 'CONCATENATE_SCRIPTS', false );

https://github.com/WordPress/WordPress/blob/master/wp-includes/script-loader.php is full of other interesting constants to explore.

I think that's a great idea @dd32! Here's what needed to make it a reality:

• Define a constants, e.g. in _runWordPressCode
• Remove the static assets from the WordPress .data bundle in prepare-wordpress.sh. There is even some prior art under the $LAZY_FILES if statement. Lazy files aren't that useful and could be removed as a concept, and the code inside that if could be repurposed.
• Rebuild the WordPress bundle with npm run build:wp and test if it worked with npm run dev

Would you like to give it a try?
