Subject: [PATCH 32/76] Fix view.php trying to do the same action as index.php

Previously, view.php considered the id parameter passed to it as
course id, not course module id (due to misunderstandings), and as
a result of this, the code tried to load the course related to that
id instead, which was plain wrong.

Subject: [PATCH 42/76] Update version.php for recent Composer migrations

Composer migrations mean, the use of its autoloader instead of
Moodle's. This helps following PSR rules better (e.g. PascalCase for
classes and camelCase for methods), as well as using third-party
packages more easily.

Subject: [PATCH 43/76] Add Globals::getPage(), add type hints for Globals
 class

Type hints are being added supposing that the Moodle files presents
somewhere in the project files, e.g. perhaps in vendor by a soft
link to Moodle lib directory. This way, the autocompletion packages
for IDEs and text-editors work great (as I tested, php-ide-serenata
for Atom works perfect). Also, after adding Psalm static analyzer,
there might be a method to escape from its errors.

Subject: [PATCH 59/76] Move InstanceDataForm back to mod_gharar_mod_form in
 mod_form.php

The parent class, i.e. moodleform_mod, extracts the module name
from the name of class using regex, and thus it sounds impossible
to have a class not in the form of mod_xx_mod_form. This is the
main reason of the change.

Also, the globals (including $CFG) required in the parent clas
makes the PSR4-based class definitions a bit weird.
