Changing 2 library names back to (less-standardized) original names.
json2.js -> json2-min.js ; jquery.localScroll.js -> jquery.localscroll.js While this is irrelevant for Wind, changing the filenames back to what we used to have ensures that we don't break contributed themes. --HG-- rename : lib/jquery.localScroll.js => lib/jquery.localscroll.js

+ * jQuery.LocalScroll
+ * Copyright (c) 2007-2010 Ariel Flesler - aflesler(at)gmail(dot)com | http://flesler.blogspot.com

+ * @projectDescription Animated scrolling navigation, using anchors.
+ * http://flesler.blogspot.com/2007/10/jquerylocalscroll-10.html
+ * @author Ariel Flesler
+ * @version 1.2.8b
+ *
+ * @id jQuery.fn.localScroll
+ * @param {Object} settings Hash of settings, it is passed in to jQuery.ScrollTo, none is required.
+ * @return {jQuery} Returns the same jQuery object, for chaining.
+ *
+ * @example $('ul.links').localScroll();
+ *
+ * @example $('ul.links').localScroll({ filter:'.animated', duration:400, axis:'x' });
+ *
+ * @example $.localScroll({ target:'#pane', axis:'xy', queue:true, event:'mouseover' });
+ *
+ * Notes:
+ * - The plugin requires jQuery.ScrollTo.
+ * - The hash of settings, is passed to jQuery.ScrollTo, so the settings are valid for that plugin as well.
+ * - jQuery.localScroll can be used if the desired links, are all over the document, it accepts the same settings.
+ * - If the setting 'lazy' is set to true, then the binding will still work for later added anchors.
+ * - If onBefore returns false, the event is ignored.
