When a third-party AMD module is provided with an included name we must
replace it with a name that we are able to use.
The structure of an AMD module define function is:
[name], [dependencies], [callback]
String, Array, Function
Each of these is (strangely) optional.
We know that the name is the only String and will always be the first,
and we can use AST to remove a provided name before adding the
Moodle-specific name.
This should be a safe change and not lead to any changes in built code,
but will make it easier to include third-party code.
An additional logging line is also included to inform developers that a
change was made.
Prior to this change all Grunt features were in a single Gruntfile.js
but this has become difficult to manage and maintain.
This commit moves the existing dependencies for component calculation
and babel moduel definition into a new .grunt directory, and
restructures the existing tasks in Gruntfile.js into separate task
configuration files.
This improves the maintainability of the Grunt build system and allows
for easier future expansion.
