Caches the global variable $l10n, which stores all translations for considerable speed improvement.

== Description ==

Upon inspection using xhProf, I realized that the PHP implementation loading the MO files is really slow.
From my tests, about 25% to 40% of the time Wordpress spends rendering the page is actually spent locating, parsing and merging all the translation files.

This plugin works by caching the whole $l10n variable holding all the text domains and overridding the `load_textdomain`.

Caching is done using serialize and written to `wp-content/uploads/l10n.pson`.
Be sure to regenerate the cache if a .mo changes.

== Installation ==
