Consider WP_List_Table public

[DavidAnderson]

WP_List_Table is far too nice to be left as private - it's too tempting to use it as a plugin developer. It's less work to just use it's lovely featurse and then do the work of keeping up to date of tracking core changes, than to re-make it for your own plugin.

Therefore I propose changing the hint in class-wp-list-table.php from:

• @access private

to:

• @access public
