fix(editor): colour PHP variables and function calls

PHP editors showed $variables and function calls in the plain text colour, because the Language Defaults that PHP inherits leave both uncoloured. The built-in schemes now give PHP its own colours for them (PHP_VAR, PHP_FUNCTION_CALL): each scheme's instance-field purple and function blue. An imported scheme's PHP_VAR / PHP_FUNCTION_CALL and the user's PHP overrides still take precedence.
