Update the TinyMCE help

[azaozz]

The content of the "Help" modal in TinyMCE needs updating. Some buttons have changed in 4.0 and it should probably have an "Accessibility" tab or section.

Perhaps there should be "What's new" section too. There are some styling changes for the more and nextpage tags and for editing images, more to come.

Noting that https://core.trac.wordpress.org/ticket/27160#comment:6 should possibly be considered, too.

What's new is a bit ephemeral for the help text, perhaps, when one considers the burden with regards to translations etc.

27100.diff​ looks good but we should explain that Paste from Word happens automatically, versus that Paste from Text should be used (which isn't entirely true).

Had a conversation with Siobhan. After reviewing the WordPress help tab content, it was clear that this TinyMCE help dialog content was duplicative and inferior. Everything here is already covered by the "Title and Post Editor" and "Inserting Media" tabs. So let's just axe the whole thing. The only thing that's useful here is the hotkeys, so let's rebrand the button as "Keyboard Shortcuts".

Patch attached as 27100.2.diff​. Any issues?

Ideally, this keyboard shortcuts dialog is a more complete, proper overlay like Gmail or Twitter (rather than be narrow and require scrolling). But this is fine for 3.9. We can give it a proper design in a future release and maybe even bring the same thing to the comments screen. Note for Gmail and Twitter you can use the shortcut ? (shift + /). We should absolutely adopt that for both screens too.

Nuke the TinyMCE help dialog as it is duplicated by help tabs. This leaves just Keyboard Shortcuts.

fixes #27100.
