Deprecation warning with PHP 8

[ghost]

Just upgraded to PHP 8 on my local and seeing this warning on a number of lines in gump.class.php:

Deprecated: Required parameter $value follows optional parameter $params in /Volumes/WIP/local/localhost/vendor/wixel/gump/gump.class.php on line 1159

Deprecated: Required parameter $value follows optional parameter $params in /Volumes/WIP/local/localhost/vendor/wixel/gump/gump.class.php on line 1232

Deprecated: Required parameter $value follows optional parameter $params in /Volumes/WIP/local/localhost/vendor/wixel/gump/gump.class.php on line 1259

Deprecated: Required parameter $value follows optional parameter $params in /Volumes/WIP/local/localhost/vendor/wixel/gump/gump.class.php on line 1276

... etc, etc, etc

Looks like there are a number of methods which have a required parameter following an optional parameter. This practice, of course, nullifies the fact of any optionality of the preceding parameter.

This should be merged with #324

Fixed now in #334

Will be released in 2.0.0 with support for php8.
