Allows display_size to use a fixed unit for easy comparison of
multiple results, and fixed decimal places for the same reason.
Improves behaviour by using consistent decimal places and a
consistent space before the unit (the previous one only has a space
before 'bytes', not before 'KB').
Of existing uses, all the ones that displayed a 'maxbytes' type
configuration setting (which are likely to have an 'exact' size
and would be better shown as 512 KB rather than 512.0 KB) have been
changed to use 0 decimal places, to preserve previous behaviour.
All the uses which were showing an actual file or memory size have
been left as default (1 decimal place).
The joubel/core and joubel/editor libraries have been moved to Moodle
namespace.
This commit adds the new namespace to the places where these classes
are used.
Besides, a couple of minor changes have been done to replace the _test.php
classname and remove some unnecessary defined('MOODLE_INTERNAL').
Take account of parent languages when requesting given library
translation. For example if we are currently using "de_kids" as the
current language, we need to recurse each language pack looking for
a matching H5P translation ("de_kids" -> "de_du" -> "de").
Existing mod_hvp pluging has a renderer to let Moodle instances
alter styles, Javascript, semantics (fields in the editor) and
content: https://github.com/h5p/moodle-mod_hvp/blob/stable/renderer.php
The approach for core_h5p is exactly the same, to let people
to reuse their existing code.
