MDL-42392 Blocks: Do not hide blocks if JS is disabled

With JS disabled, it is not possible to change the block visibility
user preference and therefore not possible to show content which was
hidden.

Since the block hiding functionality is a nicety, and we have no controls
to show and hide the blocks when JS is disabled, we should instead show the
block content regardless of the user preference.

MDL-40119 Forms: Date selector should use images for the calendar popup toggle

The calendar popup toggle must use an image, rather than an input with type
of image as the latter is actually a form of submit button, and hence it
steals the focus away from the real submit button.
MDL-43281 Blocks: Retrieve a newly created block after creating it

Although we were previously creating the DOM markup for a block region if
it did not exist, we were not making use of it.

This change ensures that we make use of that block region as part of the
blocks code.
