This adds two new admin settings to the theme appearance options.

Shows the lang menu in secure layout, langmenuinsecurelayout.
Shows the user's name in secure layout, logininfoinsecurelayout.

When the page layout is set to secure, these options will be in effect.

This includes a minor restructure of the autocomplete JS to make use of
promises and improve tracking of pending JS.

In particular it improves the way in which throttled text input is
handled to ensure that the behat does not continue until:
- typing is fully complete; and
- all possible ajax requests have been sent; and
- all possible ajax requests complete; and
- the suggestions are updated.

A number of conditions existed where behat would move on to the next
step too early in a race condition effect between Behat and Autocomplete.

* Method standard_after_main_region_html was added to the core_renderer
used by the messaging ui to message drawer

In boost we are not longer using this module, so lets limit it to
bootstrapbase only

There are 2 kinds of blocks that are undeletable. Those required by the
theme and those protected via the admin page ui. We only want the theme
ones to be auto created site wide if they don't exist - so we need to
rename the theme ones and split the logic.

Also added support for the SCSS property to be a Closure
and return content rather than simply being the name of a file.

Plus remove some pointless code.

I stayed away from big markup changes. This is a table layout so needs rewriting which is a big job.

This is a theme config setting.
They are forced on for behat always.

This functionality no longer makes sense inside Moodle now that we have
external tools like stylelint to help us with this. It was not able to
be used by any core themes.

The code was always marked as not for external use.

Look for them in the plugins DB if you still need them.
