Made most special pages "visible"; fixup for non-existent special page redirect in paths.php; rewrote Special:AllPages to have pagination (WiP, Special:SpecialPages is possibly next, depending on whether paginate_array works or not)

// UK lang variables

tinyMCE.addToLang('',{
directionality_ltr_desc : 'Direction left to right',
directionality_rtl_desc : 'Direction right to left'
});
