oik_admin_bar_menu() – Implements "admin_bar_menu" action for oik

oik_admin_bar_menu( $wp_admin_bar );

TO DO

but allow each user to override it in oik-user?

• This action hook runs after other action hooks to alter the "Howdy," prefix for 'my-account'.
• Most howdy replace plugins look for the string "Howdy," so the code won't work if the string has already been translated.
• We look for the translated version, which includes the user's display name.
• So this logic should work for localized versions.
• However, WordPress keeps changing the code.
• Which has caused it to stop working in both 4.7 and 4.8.
• See WordPress TRACs 37794 and 40342.

The structure we're changing is the node for 'my-account'. e.g.

[id] => my-account 
[parent] => top-secondary 
[title] => Howdy, <span class="display-name">vsgloik</span><img alt='' onerror='this.src="http://qw/wordpress/wp-content/themes/rngs0721/images/no-avatar.jpg"' src='http://1.gravatar.com/avatar/1c32865f0cfb495334dacb5680181f2d?s=26&d=http%3A%2F%2F1.gravatar.com%2Favatar%2Fad516503a11cd5ca435acc9bb6523536%3Fs%3D26&r=G' class='avatar avatar-26 photo' height='26' width='26' />

[class] => with-avatar 
[title] => My Account
