Use empty face instead of inheriting default

[cyrus-and]

Many faces used by this mode inherit the default face, this has the unpleasant consequence that the background is reset in Markdown code blocks with custom background, see for example:

My solution is to do something like this:

(custom-set-faces
 `(php-arithmetic-op ((t ())))
 `(php-assignment-op ((t ())))
 `(php-comparison-op ((t ())))
 `(php-function-call ((t ())))
 `(php-object-op ((t ())))
 `(php-paamayim-nekudotayim ((t ())))
 `(php-static-method-call ((t ())))
 `(php-variable-sigil ((t ()))))

But the list is growing longer and longer... Would it be possible to avoid inheriting the default face and use an empty face instead? Would there be any drawbacks?

@cyrus-and Thank you for your suggestion.
The (:inherit default) was not important, so I didn't know its side effects.

Let's remove it.

Awesome, thank you! Tested and it works.
