Both the calendar set url and switch theme links are displayed to
non-logged in users which mean they get crawled by search bots. This
prevents the search bots following these links.

The invalid type was not causing the idx to incremented, thus missing off
the final divider.

Just a copy-past text error in two comments.

Added divider support to the user menu; hardened the custom user menu against invalid input.

Was not yet ready for the prime time.

(no double newlines)

There is a new theme property 'blockrendermethod' that can be set by the
theme in its config.php and tells Moodle what method it is using to render
blocks in the layout files.
Either blocks, or blocks_for_region.
Then when adding custom block regions to a page content we ensure we use
the same method the theme is using elsewhere.

This is really a hack becuase we (I) didn't properly deprecate
blocks_for_region when I added the blocks method.

Also:
* Changed to a CSS based compacting solution
* Converted dock colours to variables
* RTL fixes for the dock

Not just pages with a visible footer.

Add additional handling for up/down/escape key presses and consolidate them
with the existing tab/shift+tab handling.

Added Style and JS to display maintenance mode timer similar
to what is done on moodle demo site for rest.
