#82499 by Jose A Reyero and a little bit from myself: send emails localized in the language needed in specific situations, and centralize mail composing operations with hook_mail()

#141996 by Jose A Reyero and myself: translation block to switch interface languages by default, and even content languages, when a translation module provides the alternate links

#154064 by pwolanin: get hook_help() up to speed to menu changes, allowing router path based lookups, and also full path argument lookup with a passed argument array

  Let this be the day where we help revolutionize the online society, and the
  way websites and web services interoperate.  Or something.

#150521 by myself: streamline locale runtime performance and clean up code by not storing empty translations

- Patch #115267 by drewish, dopry et al: simplified file uploads code, improved file API, centralized file validation, implemented quotas and fixed file previews.

#147640 by Jose A Reyero with further cleanup by myself: add language code to localization functions
This makes it possible to call these functions with a given language code when sending emails to multiple users with different languages in a request for example.

as a side effect, improve usability of the module screen by performing module
changes all at once

#143249 by Jose A Reyero: add language parameter to t() to make it possible to retrieve translations of strings for different languages, to send emails to users in their own language for example

- Patch #137415 by slantview: simplified the cache API/usages, and made it a tad smarter.  Makes it easier to program for, and easier to replace.  Will need to be documented.

- Patch #128866 by Gabor and erdemkose: make it impossible to delete the default language or the English language.

- Patch #34755 by chx et al: faster menu system.  HEAD is temporary broken and there is no upgrade path yet.

- Patch #92992 by webchick and neclimdul: clean up documentation that is superseded by the new 'by module' administration dashboard.
