resourceloader: Implement modern module loading (2/2)

* Send 'module' and 'require' parameters to module closures.
  This depends on Ia925844cc22f143 being deployed one cycle earlier.
* Patch Moment and OOjs to ensure these libraries continue to expose
  their module as globals as well. AMD/UMD-compatible libraries
  only expose a global *OR* an export, not both. We need both
  for back-compat.
* Update pluralRuleParser to make use of module export to allow
  usage via require().

To test, check out the patch and run:
> mw.loader.load('moment');
> mw.loader.require('moment')()
> mw.loader.require('moment')('2011-04-01').fromNow()
