Changes

Hi Julian,

A few changes and optimisations.  I've put into a few commits so you can cherry pick as you wish.

I've added an English Pirate language file as seemed required :)

I put back the font URL themewww code as the new form will not work without 'file_get_contents' to serve the font which currently would not work with the 'url' component of the attribute in CSS.

I've added an English US language file containing the changes only between en and en_us.

The function 'current_theme()' is in 'depreciatedlib.php' and therefore should not be used.  Also decided to hard code the 'essential' theme name to solve the $PAGE issue as pragmatically you'd be changing the function names in lib.php anyway.

Cheers,

Gareth
