Rework loadL10N method.

Changelog excerpt:
- Reworked the loadL10N method, how it handles HTTP_ACCEPT_LANGUAGE,
  improved rule assignment, added some assumptions for supported L10N, and
  added the ability to defer non-supported L10N to supported L10N where
  sufficiently similar to be acceptable.
