Hide deprecation errors from display

[edjeavons]

It's not uncommon for plugins to throw deprecated code messages and displaying them breaks website functionality, e.g. if the error happens before headers are written.

I don't know if this is even possible in WordPress but it would be nice if WP_DEBUG_DISPLAY could be left enabled in config/environments/development.php and have a new setting for it to exclude deprecation error messages.

We generally don't want to disable errors altogether in a development environment because mose other types of message important for us to know about.

Good idea. This might do what we are looking for, or the principle can be added to Nebula.
