With the introduction of user-specific languages in [38705] it's necessary to be able to switch translations on the fly. For example emails should be sent in the language of the recipient and not the one of the current user.
This introduces a new `WP_Locale_Switcher` class which is used for switching locales and translations. It holds the stack of locales whenever `switch_to_locale( $locale )` is called. With `restore_previous_locale()` you can restore the previous locale. `restore_current_locale()` empties the stack and sets the locale back to the initial value.
`switch_to_locale()` is added to most of core's email functions, either with the value of `get_locale()` (site language) or `get_user_locale()` (user language with fallback to site language).

PHP7 is deprecating PHP4 style constructors, so we need to modify our code to have _construct methods that fire before the named PHP4 style constructors. The PHP4 style constructors will call the PHP5 style constructor in case it is being called directly (usually via parent::METHOD).
This modifies external libraries to add PHP5 style constructors, but doesn't add a notice for when they are used. In WordPress core code, PHP4 style constructors are being given a call to _deprecated_constructor. To the PHP4 style constructor I say "I know that I can't take no more | It ain't no lie | I wanna see you out that door | Baby, bye, bye, bye..."

If the function has no need for `@param` or `@return`, do an archeaological dig to find `@since`.

* All WordPress files move to a src/ directory.
* New task runner (Grunt), configured to copy a built WordPress to build/.
* svn:ignore and .gitignore for Gruntfile.js, wp-config.php, and node.js.
* Remove Akismet external from develop.svn. Still exists in core.svn.
* Drop minified files from src/. The build process will now generate these.
