Update for Genesis 2.9 ... 3.0.3 ... 3.1.2

[bobbingwide]

Update dependency on Genesis to 2.9.0 and take improvements into account.
e.g. Remove the need to set CHILD_THEME_ constant(s)... if appropriate.

[bobbingwide]

Genesis v3.0.3 was released recently. Can we now update the theme to work with Genesis 3.0.3? Does this mean applying the latest genesis-sample?

[bobbingwide]

Genesis 3.1.0 was released on 21st August 2019. We now need to support the latest version: 3.1.2
This includes making a change for the deprecated filter genesis_footer_creds_text. Use genesis_pre_get_option_footer_text. See also bobbingwide/genesis-SB#18

How it once was...

In genesis-a2z, after updating to use v3.1.0 of the Genesis theme framework there were still 4 CHILD_THEME_* constants in functions.php This table summarised their usage.

Constant	Value / Example	Usage
CHILD_THEME_NAME	'Genesis a2z'	Used by Genesis to construct CHILD_THEME_HANDLE
CHILD_THEME_URL	'https://www.oik-plugins.com/oik-themes/genesis-a2z'	Unused?
CHILD_THEME_VERSION	wp_get_theme()->get( 'Version' )	Used by genesis_get_theme_version()
CHILD_THEME_HANDLE	sanitize_title_with_dashes( wp_get_theme()->get( 'Name' )	Used generating inline styles

Note: For bespoke child themes that are delivered from bobbingwide.com the child theme URL should be of the form https://www.bobbingwide.com/blog/oik-themes/theme_name.

What it should be

It would appear that none of the above is necessary with Genesis 3.1.0
The values are automagically determined by the framework from the style.css file.

Constant| Style.css line used | Example
------------- |
CHILD_THEME_NAME | Theme Name: | Genesis a2z
CHILD_THEME_URL | Theme URI: | https://www.oik-plugins.com/oik-themes/genesis-a2z
CHILD_THEME_VERSION | Version: or, if SCRIPT_DEBUG is true the current timestamp | 2.0.0
CHILD_THEME_HANDLE | n/a | genesis_get_theme_handle()

So it would appear that none of this logic is necessary any more.

//* Child theme (do not remove) 
define( 'CHILD_THEME_NAME', 'Genesis a2z' );
define( 'CHILD_THEME_URL', 'https://www.oik-plugins.com/oik-themes/genesis-a2z' );
if ( defined( 'SCRIPT_DEBUG' ) && SCRIPT_DEBUG ) {
	$timestamp = filemtime( get_stylesheet_directory() . "/style.css" );
	define( 'CHILD_THEME_VERSION', $timestamp );
} else { 
	//define( 'CHILD_THEME_VERSION', '1.3.0' );
	define( 'CHILD_THEME_VERSION', wp_get_theme()->get( 'Version' ) );
}
// Defines constants to help enqueue scripts and styles.
define( 'CHILD_THEME_HANDLE', sanitize_title_with_dashes( wp_get_theme()->get( 'Name' ) ) );

OK. So Genesis is 3.2.1 now. Anything else we need to do?
