jdlrobson 5cd10ce862 Reduce JS loaded on critical path
As a precursor to incorporating a new language switcher in the new
version of Vector I'd like to improve the performance of loading
the switcher.

It seems most code can be deferred until the language selector
button is clicked.

This shaves around 30kb of resources off the critical path for
most users. There's potential here for a positive performance
impact so we should follow up the deployment by checking the
associated performance graphs to see if there's improvement.

Note, if the compact personal links feature is enabled
there is no performance saving for now. This will be addressed in follow
ups.

== Universal Language Selector ==
The Universal Language Selector extension (ULS) provides a flexible way to
configure and deliver language settings like interface language, fonts, and
input methods (keyboard mappings). This will allow users to type text in
different languages not directly supported by their keyboard, read content in a
script for which fonts are not available locally, or customise the language in
which menus are displayed.

== Installation ==
For a very, very quick start add the following lines to LocalSettings.php of
your MediaWiki setup:

wfLoadExtension( 'UniversalLanguageSelector' );

By default, ULS will appear at personal toolbar position. If you want ULS at
interlanguage position, add the following line:

$wgULSPosition = 'interlanguage';

The MediaWiki Universal Language Selector project uses jquery.uls:

Its development is at Wikimedia Github account. Any fixes to lib/ should happen
at Github. Follow the build instructions of jquery.uls to create jquery.uls.js.
