Help with readability by using module.exports and require rather than the MobileFrontend
provided mw.mobileFrontend module manager (and avoid adopting webpack at this time)
Replace usages of mw.mobileFrontend.require with local require and module.exports
(compatible with RL or Node implementation)
Changes:
* Notifications modules are merged into skins.minerva.scripts and initialised
via a client side check.
* new file overlayManager for exporting an overlayManager singleton
rather than being hidden inside resources/skins.minerva.scripts/init.js
* All M.define/M.requires swapped out for require where possible
The `define` method is now forbidden in the repo.

Suppress the redlink drawer for User namespace pages. The redlink drawer
prompts the user to create a missing page but this hinders the usual
workflow for User page visits specifically. A User page is connection to
an account's contributions, age, and other activities and encouraging
the creation of a missing User page when trying to view these
connections is a hindrance, especially if the missing User page is not
associated with the current user.
