Add a (simple) way to disable the help tab.

[koopersmith]

Currently, disabling the default help takes some filter-filled goodness. We should have a better, API-sanctioned way.

As for use cases — the new About screen in core is a prime example.

The default help might change once the sidebar and such is set, so we'll use this ticket to track it.

I'm thinking a method that either kills (or sets) the default help, or all help.

One option would be a simple filter that we could do either before admin-header is included, or that a plugin could do on load-$pagenow:

add_filter( "show_help_" . get_current_screen()-id, '__return_false' )

Or something like that.

Alternative from Ryan: "No default help. It's kinda useless and those links are in the W menu." I like.

19154.diff​ removes the default default help (keeps the filter).

No default help.

In [19185]:

Remove default help text. Keep the default_help filter in place for plugins. fixes #19154.
